# 1 INTRO

iCalcreator is a PHP class package managing iCal files, supporting (non-)calendar systems and applications to process and communicate calendar information like events, agendas, tasks, reports, totos and journaling information.

The iCal standards are rfc5545/rfc5546 (rfc2445/rfc2446).

iCalcreator features create, parse, edit and select calendar and calendar components.

The iCalcreator package, built of a calendar class with support of a function class and helper functions, are calendar component property oriented. For iCalcreator 2.18 version (and later), PHP version >= 5.2.0 is required, due to the use of PHP DateTime class (and related functions) .

The iCalcreator main class, utility class and helper functions are all included in the "iCalcreator.class.php" file.

More iCalcreator supplementary, "howto" and coding support information will be found at kigkonsult.se iCalcreator implement examples and test pages. A strong recommendation is to have this document open in parallell when exploiting the link.

iCalcreator will support hiphop if the HDF AllDynamic option is enabled (the helper iCal2XML function is excluded).

## 1.1 Standards

#### iCal

The iCalendar format, iCal, as described in

rfc5545
  "Internet Calendaring and Scheduling Core Object Specification (iCalendar)"
rfc5546
  "iCalendar Transport-Independent Interoperability Protocol (iTIP)"
  Scheduling Events, BusyTime, To-dos and Journal Entries

. ..allows for the capture and exchange of information normally stored within a calendaring and scheduling application.

and

. ..is an exchange format between applications or systems.

rfc5545 and rfc5546 obsoletes, respectively, rfc2445 and rfc2446.

A short iCal description is found at Wikipedia. If You are not familiar with iCal, read this first! Knowledge of calendar protocol rfc5545/rfc5546 is to recommend.

Any references to rfc2445, below, corresponds to rfc5545.

#### xCal

iCalcreator also supports xCal (iCal xml) rfc6321, "xCal: The XML Format for iCalendar", to be downloaded from

rfc6321
  "xCal: The XML Format for iCalendar"

A short xCal description is found at Wikipedia.

The older xCal format, as defined in "http://www.ietf.org/internet-drafts/draft-ietf-calsch-many-xcal-01.txt" (but no longer found), still works in this version but will not be maintaned and will be removed in future versions.

## 1.3 Versioning

The release numbering convention used is major.minor(.micro / suffix).

Major
  Indicates a very large change in the core package. Rewrites or major milestones.
Minor
  Significant amount of feature addition/modification.
  odd number - development/experimental release
  even number - production release
Micro
  Primarily bug fix and maintenance number.
Suffix
  rc1 for first release candidate etc.

The release plan is based on yearly releases with exception of emergency releases.

## 1.6 Install

### 1.6.1 Basic

Unpack to any folder
- add this folder to your include-path
- or unpack to your application-(include)-folder

Add

require_once "[folder/]iCalcreator.class.php";

to your PHP-script.

If using PHP version 5.1 or higher, the default timezone may need to be set.

Creating a new iCalcreator object instance/component instance, review config settings.

[index] [top]

## 1.7 Additional Descriptors

The following properties (as described in wikipedia:iCal) may be required when importing iCal files into some calendaring software (MS etc.):

on calendar level
  METHOD property (value PUBLISH etc.)
  X-WR-CALNAME x-property
  X-WR-CALDESC x-property
  X-WR-RELCALID x-property (Read more info about UUID.)
  X-WR-TIMEZONE x-property
on component level
  DTSTAMP property (in iCalcreator created automatically, if not set)
  UID property (in iCalcreator created automatically, if not set)
on component level in a vtimezone component
  X-LIC-LOCATION x-property

Example

A strong recommendation is also to set config unique_id, creating a new vcalendar/component instance, to ensure accurate setting of all components UID property, especially before parse. Also setting of config timezone ("TZID" and "X-WR-TIMEZONE" below) is to recommend.

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "TZID" => "Europe/Stockholm" ); $vcalendar = new vcalendar( $config ); $vcalendar->setProperty( "method", "PUBLISH" ) $vcalendar->setProperty( "x-wr-calname", "Calendar Sample" ); $vcalendar->setProperty( "X-WR-CALDESC", "Calendar Description" ); $uuid = "3E26604A-50F4-4449-8B3E-E4F4932D05B5"; $vcalendar->setProperty( "X-WR-RELCALID", $uuid ); $vcalendar->setProperty( "X-WR-TIMEZONE", "Europe/Stockholm" ); .. .

## 1.8 Addendum

For iCalcreator usage, coding samples and tests, visit the public kigkonsult.se test resource.

Examples how to employ iCalcreator in software development
  dbiCal, an iCal file PHP database backend solution.
  The iCal file event editor
  tinycal, calendar-in-a-box.

There are free iCal/xCal icons (use as buttons on a web page?) to download here.

The PHP coding in this document or "coding samples" (above) are only for display of usage, recommendation is to use a coding standard, the following, incomplete, list is a good start;

  PHP Framework Interop Group Basic Coding Standard
  pear Coding standards
  WordPress PHP Coding Standards
  Zend Framework Coding Standard

If not set, the DTSTAMP and UID properties are automatically created by iCalcreator
for vevent,vtodo, vjournal and vfreebusy components
when using iCalcreator object methods saveCalendar or returnCalendar
or when fetching DTSTAMP/UID property value with the component function getProperty.

# 3 Function list

## 3.1 iCalcreator object methods

### 3.1.1 Constructors

#### 3.1.1.1 vcalendar

Create a new VCALENDAR object.

Format

vcalendar::vcalendar( [ config ] )

config = array, review configuration options.

Basic example

<?php .. . $config = array( "unique_id" => "kigkonsult.se" ); $vcalendar = new vcalendar( $config ); ...

The calendar property PRODID and each component property UID are AUTOMATICALLY generated in iCalcreator, if not set manually, and based on the configuration unique_id.

Extended example

<?php .. . $tz = "Europe/Stockholm" $config = array( "unique_id" => "kigkonsult.se" "TZID" => $tz ); $vcalendar = new vcalendar( $config ); $vcalendar->setProperty( "X-WR-TIMEZONE", $tz ); .. . .. . // insert components or parse an iCal file (and edit components) .. . $xprops = array( "X-LIC-LOCATION" => $tz ); iCalUtilityFunctions::createTimezone( $vcalendar, $tz, $xprops ); .. .

The TZID config key and value (timezone) is supplied when setting DTSTART, DTEND, DUE or RECURRENCE-ID, if not set manually, a TZID auto completion.

Some calendar software may also require calendar property X-WR-TIMEZONE and vtimezone component with property X-LIC-LOCATION, review createTimezone, a function in iCalUtilityFunctions class.

[index] [top] [up]

#### 3.1.1.2 vevent

Format 1

Create a new VEVENT object using an iCalcreator object component factory-method, returning a reference to the new component.

vcalendar::newComponent( "vevent" )

Example

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "TZID" => "Europe/Stockholm" ); $vcalendar = new vcalendar( $config ); ... $vevent = & $vcalendar->newComponent( "vevent" ); $vevent->setProperty(... ...

Format 2

Create a new VEVENT object.

vevent::vevent( [ config ] )

startYear : (int) start year (4*digit), default current year startMonth : (int) start month (1-2*digit), default current month startDay : (int) start day (1-2*digit), default current day endYear : (int) end year (4*digit), default startYear endMonth : (int) end month (1-2*digit), default startMonth endDay : (int) end day (1-2*digit), default startDay cType : (mixed) calendar component type(-s), (string/array) ("vevent", "vtodo", "vjournal", "vfreebusy") (bool) FALSE (default) => all flat : (bool) TRUE => output : array[] (ignores split) component where recurrence pattern exists within period FALSE (default) => output : array[Year][Month][Day][] any : (bool) TRUE (default) => select components with recurrence within period FALSE => only components that starts (DTSTART) within period split : (bool) TRUE (default) => one component copy for every day it occurs within the period FALSE => one occurrence of component in output array, start date/recurrence (start) date valid flat any split combinations (defaults in upper case) 1 FALSE TRUE TRUE 2 FALSE TRUE false 3 FALSE false [false] (split set to false if flat=FALSE and any=false) 4 true TRUE [false] (split set to false if flat=true) 5 true false [false] (split set to false if flat=true) If flat is set to FALSE, output array is sorted in 'Y-m-d h-i-s' asc. order.

Example

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "directory" => "import", "filename" => "file.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); $events_arr = $vcalendar->selectComponents( 2007, 11, 1, 2007, 11, 30, "vevent" ); // select all events occurring 1-30 nov. 2007 foreach( $events_arr as $year => $year_arr ) { foreach( $year_arr as $month => $month_arr ) { foreach( $month_arr as $day => $day_arr ) { foreach( $day_arr as $event ) { $currddate = $event->getProperty( "x-current-dtstart" ); // if member of a recurrence set, returns // array(" x-current-dtstart", // <(string) date("Y-m-d [H:i:s][timezone/UTC offset]")>) $startDate = $event->getProperty( "dtstart" ); $summary = $event->getProperty( "summary" ); $description = $event->getProperty( "description" ); .. . .. .

format 2

Using this format, the iCalcreator object method selects components based on specific property value(-s).

Supported Descriptive Component Properties
  CATEGORIES
  LOCATION
  PRIORITY
  RESOURCES
  STATUS
  SUMMARY
Supported Relationship Component Properties
  ATTENDEE *1
  CONTACT
  ORGANIZER *1
  RELATED-TO
  URL
  UID

*1
  ATTENDEE and ORGANIZER search values must be prefixed by (upper case) protocol like "MAILTO:chair@ical.net".

For the property SUMMARY, if a search value (any case) exists within property value, a hit is found. For the other properties an exact (strict case) match is required. Multiple search properties may coexist.

To retrieve specific iCalcreator instance property values, searching ALL components, use getProperty (Format 2).

To get components based on property values, use getComponent (Format 5).

vcalendar::selectComponents( searchArray )

Outputs an array of matched (unique) components in UID order.

searchArray : (array) *( propertyName => propertyValue ) propertyName : (string) above (any case) propertyValue : (string) value / (array) ( *[ (string) value] )

Example

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "directory" => "import", "filename" => "file.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); $searchArray = array( "PRIORITY" => array( 1, 2, 3, 4 )); $highPrioArr = $vcalendar->selectComponents( $searchArray ); // select all components with PRIORITY set to high (1-4) if( !empty( $highPrioArr )) { $highPrioCal = new vcalendar( array( "unique_id" => "kigkonsult.se" )); $highPrioCal->setProperty( "X-WR-CALDESC", "High priority events" ); foreach( $highPrioArr as $highPrioComponent ) $highPrioCal->setComponent( $highPrioComponent ); $highPrioCal->returnCalendar(); } .. .

#### 3.1.3.6 setComponent

Replace or update component in the iCalcreator object instance. Also add a calendar component to the iCalcreator object instance when calendar component is created with the procedural (non-factory) method, see example VEVENT, format 2.

A successful update returns TRUE.

format 1

Insert last in component chain.

vcalendar::setComponent( component ) addComponent( component ) // alias

component = (object) iCalcreator component instance

addComponent, may be removed in future versions.

format 2

Insert/replace component with order number (1st=1, 2nd=2.. .). If replace and orderNumber is not found, component is inserted last in chain.

vcalendar::setComponent( component, orderNumber )

component = (object) iCalcreator component instance int = (int) order numder

format 3

Replace component with component type and 1st alt. component order number. If orderNumber is not found, component is inserted last in chain.

vcalendar::setComponent( component, componentType [, componentSuborderNo])

component = (object) iCalcreator component instance componentType = (string) component type componentSuborderNo = (int) component Suborder Number

format 4

Replace component with UID. N.B UID is NOT set for ALARM / TIMEZONE components. If UID is not found, component is inserted last in chain.

vcalendar::setComponent( component, UID )

component = (object) iCalcreator component instance

Example

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "filename" => "file.ics"); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); $vevent = vcalendar->getComponent( 1 ); // fetch first EVENT $vevent->setProperty( "dtstart, 2006, 12, 24, 19, 30, 00 ); // update DTSTART property $vcalendar->setComponent( $vevent, 1 ); // replace first component .. .

### 3.1.4 iCalcreator calendar methods

#### 3.1.4.1 parse and merge

Parse iCal file(-s) or string/array calendar content into a single iCalcreator object instance (components, properties and parameters), including multiple vcalendars (within a single ICS file) parse, e.g. Oracle Calendar exports.

As long as php.ini directive "allow_url_fopen" is enabled, remote files, URLs; protocol "http" ("webcal"), are supported. A remote file, URL, must be prefixed by "http://" ("webcal://") and suffixed by a valid filename.! Recommendation is to download (cache) remote file before parsing, due to execution time and control.

If missing, component property UID is created when parsing. For that reason UNIQUE_ID might need to be set before parsing, Se examples below.

Notice date restriction!

If major parse error occurs (like file access error, invalid calendar file or calendar file without components), FALSE is returned.

Minor errors like non-standard line-endings, initial and trailing empty lines as well as files without proper end line(-s) (i.e. missing component end and/or "END:CALENDAR" iCal directives) are managed.

Non-standard iCal properties (except the X-properties) are ignored.

Format

vcalendar::parse( [ textToParse ] )

textToParse = (string) calendarContent ex. result from - file_get_contents( "filename") (array) calendarContent ex. result from - file( "filename", FILE_IGNORE_NEW_LINES )

parse example 1

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "filename" => "file.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); .. .

parse example 2

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "url" => "http://www.ical.net/calendars/calendar.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); .. .

parse example 3

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "url" => "http://www.ical.net/calendars/calendar.ics" ); $vcalendar = new vcalendar( $config ); ... $str = array( "BEGIN:VCALENDAR", "PRODID:-//kigkonsult.se//NONSGML kigkonsult.se iCalcreator 2.16.6//", "VERSION:2.0", "BEGIN:VEVENT", "DTSTART:20101224T190000Z", "DTEND:20101224T200000Z", "DTSTAMP:20101020T103827Z", "UID:20101020T113827-1234GkdhFR@test.org", "DESCRIPTION:example", "END:VEVENT", "END:VCALENDAR"); $vcalendar->parse( $str ); ...

[index] [top] [up]

#### 3.1.4.3 returnCalendar

Redirect the iCalcreator object instance content to user browser. Filename, addressed to browser, is automatically generated if missing or not set;
$filename = date( "YmdHis" ).".ics" .

Format

vcalendar::returnCalendar( [ utf8Encode [, gzip ]] )

utf8Encode = (bool) TRUE: utf8 encoded output, FALSE: (default) no encoding gzip = (bool) TRUE: gzip compressed output Header "Content-Length" only sent when gzip=TRUE FALSE: (default) no compressing

Example 1

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "TZID" => "Europe/Stockholm" ); $vcalendar = new vcalendar( $config ); .. . $vevent = & $vcalendar->newComponent( "vevent" ); $vevent->setProperty( "dtstart", array( "year" => 2007 , "month" => 4 , "day" => 1 , "hour" => 19 )); $vevent->setProperty( "duration", 0, 0, 3 )); $vevent->setProperty( "LOCATION", "Central Plaza" ); $vevent->setProperty( "summary", "PHP summit" ); .. . $vcalendar->returnCalendar(); .. .

Example 2

[index] [top] [up]

#### 3.1.4.4 saveCalendar

Save the iCalcreator object instance in a file, uses present directory if directory not set, filename is automatically generated if missing or not set;
$filename = date( "YmdHis" ).".ics" .

Directory/filename must be writeable, delimiter default PHP constant DIRECTORY_SEPARATOR.

If file error occurs, FALSE is returned.

Format

vcalendar::saveCalendar ( [ directory [, filename [, delimiter ]]] )

directory = (string) directory, default FALSE filename = (string file name, default FALSE delimiter = (string) path directory/filename separator, default FALSE

Parameters for directory/filename/delimiter, kept for backward compatibility, may be removed i future versions. Recommendation is to use setConfig, Se example below.

Example

<?php .. . $vcalendar->setConfig( array( "directory" => "depot", "filename" => "calendar.ics" )); $result = $vcalendar->saveCalendar(); if( !$result ) echo "error when saving.. ." ...

[index] [top] [up]

#### 3.1.4.5 sort

Format 1

Sort created/parsed calendar components on the following (prioritized) keys:
1 - X-CURRENT-DTSTART - X-CURRENT-DTEND/X-CURRENT-DUE
(if created in iCalcreator object method selectComponents)
1 - DTSTART - DTEND alt. DURATION (VEVENT and VFREEBUSY components)
1 - DTSTART - DUE alt. DURATION (VTODO components)
1 - DTSTART (VJOURNAL components)
2 - CREATED / DTSTAMP
3 - UID
A date value, like "DTSTART;VALUE=DATE:20120717", are sorted before a datetime value.
VTIMEZONE component(-s) is always placed first (ordered by TZID). The STANDARD / DAYLIGHT sub-components are sorted (on asc. key DTSTART) when calling createCalendar (or returnCalender).
ALARM sub-components, if exists, are not sorted.

vcalendar::sort()

Example

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "directory" => "import", "filename" => "file.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); $vcalendar->sort(); $vcalendar->returnCalendar(); ...

Format 2

Sort created/parsed calendar components based on specific property values and ascending order. If a property is not set in component, an empty sort key is used (i.e. sorted first).

vcalendar::sort( sortArgument )

sortArgument: (string) "ATTENDEE" * / "CATEGORIES" * / "CONTACT" * / "DTSTAMP" / "LOCATION"" / "ORGANIZER" / "PRIORITY" / "RESOURCES" * / "STATUS" / "SUMMARY" / "URL" / "UID" **.

*) For a property where multiple occurrence may exist (ATTENDEE, CATEGORIES, CONTACT, RESOURCES) lowest (alphabetic) value is used as sort key.

**) For multiple components with the same UID, components with RECURRENCE-ID / SEQUENCE set are sorted first (on asc. values).

#### 3.1.4.6 useCachedCalendar

If recent version of local (non-empty and saved) calendar file exists, an HTTP redirect header is sent otherwise FALSE is returned.

Format

vcalendar::useCachedCalendar( [ timeout ] )

vcalendar::useCachedCalendar( [ directory [, filename [, delimiter [, timeout ]]]] )

directory = (string) directory, default FALSE filename = (string file name, default FALSE delimiter = (string) path directory/filename separator, default FALSE timeout = (int) default 3600 sec Second format with parameters for directory/filename/delimiter,
kept for backward compatibility, may be removed i future

#### 3.1.5.7 Delimiter

Directory/filename delimiter.

Default PHP constant DIRECTORY_SEPARATOR. If used, must be set BEFORE filename!

[index] [top] [up]

#### 3.1.5.8 Directory

Local directory to store/read iCal files.

Default ".".

Directory must be set BEFORE filename and must exist and be writeable otherwise FALSE is returned. If set using an config array and together with Filename, Directory are set automatically first. When setting directory, the PHP realpath function is applied to speed up parse/saveCalendar methods. When setting Directory, any previously set URL is removed.

[index] [top] [up]

#### 3.1.5.9 Fileinfo

Only available in iCalcreator object method getConfig, giving information in array format about directory, filename and filesize.

Example

<?php .. . $fileinfo = $vcalendar->getConfig( "fileinfo" ); .. .

output = array( <directory>, <filename>, <filesize> )

[index] [top] [up]

#### 3.1.5.10 Filename

iCal local file name, default created like (if not set):

$filename = date( "YmdHis" ).".ics";

$filename = date( "YmdHis" ).".xml"; // if format set to "xcal"

If not set, filename is created when requested, ex. in iCalcreator object methods saveCalendar or getConfig("filename").

Local filename must be set AFTER setting directory (and opt. delimiter)! Filename (and opt. directory) must be readable/writeable otherwise FALSE is returned.

[index] [top] [up]

#### 3.1.5.11 Filesize

Only when getting configuration (using iCalcreator object method getConfig).
Returns the size of the file in bytes, to be invoked
- after "saveCalendar()"
or
- after a "setConfig( "directory" / "filename" )" and before/after "parse()".
Getting the filesize for a remote file (URL) will always return zero.

[index] [top] [up]

#### 3.1.5.12 Format

Format for the iCalcreator object instance output, "iCal"/"xCal", any case.

"iCal" is default ([RFC5545]), "xCal" force xml formatted output, according to
"draft-ietf-calsch-many-xcal-01.txt" (now obsolete).

For converting to and from XML, according to rfc6321, "xCal: The XML Format for iCalendar",use functions
- iCal2XML converts an iCalcreator object instance to XML
- XML2iCal converts XML (string/file) to an iCalcreator object instance.

[index] [top] [up]

#### 3.1.5.13 Language

Language for the iCalcreator object instance and component TEXT value properties as defined in [RFC5646].

Default empty.

If NOT set in TEXT property parameters, language from component instance "setConfig( "language", ..)" method will be used, if set, otherwise language from calendar method "setConfig( "language", ..)" will be used, if set.

The calendar property PRODID is always recreated when setting (calendar) language (, note Unique_id, below).

[index] [top] [up]

#### 3.1.5.14 NewlineChar

Character(s) used for carriage return + line feed (CR+LF).

Default "\r\n" as defined in [RFC5545].

[index] [top] [up]

#### 3.1.5.15 setPropertyNames

Returns array of property names for all set properties in component. "X-PROP" will be used when X-properties are set.

[index] [top] [up]

#### 3.1.5.16 TZID

General timezone, will be used if no TZID parameter is supplied when setting DTSTART, DTEND, DUE or RECURRENCE-ID, a TZID auto completion.

Default empty.

Note, some calendar software may also require calendar property X-WR-TIMEZONE and vtimezone component property X-LIC-LOCATION (to be set manually, examine also the createTimezone function).

[index] [top] [up]

#### 3.1.5.17 Unique_id

"Unique_id" is used in calendar property PRODID and component property UID, both created automatically (, if not setting UID manually.

PRODID The identifier is RECOMMENDED to be the identical syntax to the [RFC 822] addr-spec. A good method to assure uniqueness is to put the domain name or a domain literal IP address of the host on which.. .

Default AUTOMATICALLY generated by using PHP function gethostbyname( $_SERVER["SERVER_NAME"] ) when running in a web server environment or "localhost" when using command line interface. Used when setting other (domain) name than server name.

The calendar property PRODID is always recreated when setting unique_id.

If missing, the component property UID is created at first use of iCalcreator object methods createCalendar, returnCalendar or saveCalendar

A strong recommendation is always to set unique_id, creating a new iCalcreator object or component instance, to ensure accurate creation of all components UID property, also before parse, in case of missing UID.

[index] [top] [up]

#### 3.1.5.18 URL

When reading remote files or resources with URL (using the parse() method), protocol "http" ("webcal") and "https" are supported.

When setting URL, the previously set Directory is removed.

A remote file is identified by the file suffix ".ics", otherwise the URL is classified as a resource. When setting URL to a remote iCal file, only directory need to be (re-)set, filename remains unchanged (i.e. 1. set URL, 2. parse, 3. set directory, 4. saveCalendar). The URL remote file file part can be retrieved by the vcalendar method getConfig( "filename" ). When using a resource, filename is unset (note filename, above).

Example

Parse of remote file, then local save in "depot" folder, using original filename

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "url" => "http://www.iCal.net/depot/calendar.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); $vcalendar->sort(); .. . .. . $vcalendar->setConfig( "directory", "depot" ); $vcalendar->saveCalendar(); .. .

## 3.2 Calendar component property method list

All iCalcreator component object property methods for get/set data.
For property format in detail, see RFC2445 - Internet Calendaring and Scheduling Core Object Specification (iCalendar).

Notice: for properties and DATE-TIME with UTC time.

RFC2445: The date with UTC time, or absolute time, is identified by a LATIN CAPITAL LETTER Z suffix character (US-ASCII decimal 90), the UTC designator, appended to the time value. For example, the following represents January 19, 1998, at 0700 UTC:

DTSTART:19980119T070000Z

The TZID property parameter MUST NOT be applied to DATE-TIME properties whose time values are specified in UTC.

Notice: date limitation.
Due to a limitation in PHP date functions, e.g. mktime, strtotime, a date (e.g. while setting DTSTART property) before "January 1 1970 00:00:00 GMT" may force a PHP date function to generate an error or set date to "January 1 1970".

### 3.2.1 deleteProperty

Generic iCalcreator object instance delete property method,simplifying removal of calendar properties.
FALSE is returned if no property exists or when end-of-properties at consecutive function calls.

Format

calendarComponent::deleteProperty( [ PropName [, order ] )

propName = (string) case independent, [RFC5545] component property names, unknown/missing propName will be used as X-property. order = (int) if missing 1st/next occurrence, used with multiply (property) occurrences

Example

Remove all COMMENT properties in first event component.

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "directory" => "import", "filename" => "file.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); $event = $vcalendar->getComponent( "vevent" ); while( $event->deleteProperty( "comment" )) continue; .. .

[index] [top] [up]

### 3.2.2 getProperty

Generic iCalcreator component get property method, simplifying fetch of properties.

FALSE is returned if no property exists or when end-of-properties at consecutive function calls.

Using the non-standard directive "GEOLOCATION", iCalcreator returns output supporting
ISO6709 "Standard representation of geographic point location by coordinates",
by combining the LOCATION and GEO property values (only if GEO is set).

Format

calendarComponent::getProperty( PropName [, order [, complete ]] )

propName = (string) case independent, [RFc5545] component property names, unknown/missing propName will be used as X-property. order = (int) if missing/FALSE 1st/next occurrence, otherwise with multiply occurrences (1st=1, 2nd=2.. .) complete - (bool) FALSE (default): output only property value TRUE : output = array("value" => <value> ,"params"=> <parameter array>)

Example

<?php .. . $config = array( "unique_id" => "kigkonsult.se", "directory" => "import", "filename" => "file.ics" ); $vcalendar = new vcalendar( $config ); $vcalendar->parse(); while( $vevent = $vcalendar->getComponent( "vevent" )) { $dtstart = $vevent->getProperty( "dtstart" ); // one occurrence $description = $vevent->getProperty( "description" ); // one occurrence while( $comment = $vevent->getProperty( "comment" )) { // MAY occur more than once .. . } } .. .

[index] [top] [up]

### 3.2.3 parse

Parse iCal component property text from a string or an array. Each string/array row must be strict RFC5545 formatted, i.e. begin with a property name.

Complete ALARMs, all properties included, in array format and first array row as "BEGIN:VALARM", last as "END:VALARM" as well as TIMEZONE and standard/daylight subcomponents.

If major parse error occurs (like invalid calendar structure or no calendar components), FALSE is returned.

Minor errors like non-standard line-endings, initial and trailing empty lines as well as files without proper end line(-s) (i.e. missing component end iCal directives) are managed.

Except the X-properties, non-standard properties are ignored.

propName = (string) case independent, [RFC5545] component property names, unknown propName will be regarded as (a non-standard) X-property. Proparg_n = (mixed) property content Last property argument is a (optional) property dependent parameters array( *[(string) key => (string) value ] ). A non-standard (, experimental) parameter key MUST be prefixed by "X-".

Example

<?php .. . $vevent = & $vcalendar->newComponent( "vevent" ); $vevent->setProperty( "dtstart" , array("year"=>2007,"month"=>4,"day"=>1,"hour"=>19)); $vevent->setProperty( "duration", 0, 0, 3 )); $vevent->setProperty( "LOCATION", "Central Plaza" ); $vevent->setProperty( "summary", "PHP summit" ); .. .

DTSTART;VALUE=DATE:20071201
DTEND;VALUE=DATE:20071202.

##### Create DTEND

##### Delete DTEND

Remove DTEND from component.

Format

calendarComponent::deleteProperty( "DTEND" )

Example

<?php .. . $vevent->deleteProperty( "DTEND" ); .. .

##### Get DTEND

If set, returns property value, otherwise FALSE.

Format 1

calendarComponent::getProperty( "DTEND" )

output = dtendDate1

Format 2

calendarComponent::getProperty( "DTEND", FALSE , TRUE )

output = array( "value" => dtendDate1 , "params" => params2 )

Example

<?php .. . $dtend = $vevent->getProperty( "dtend" ); .. .

##### Set DTEND

Insert property value. If DATE value type is expected, "VALUE" = "DATE" must be set (in params2) otherwise DATE-TIME (default) value type is set.

If no timezone parameter (tz or tzidparam below) is set (i.e.local time) and config TZID is set, date-time values will be set WITH timezone from config. Notice, use function transformDateTime to change a datetime from one time zone to another.

Parameters, if any, will be ordered as prescribed in [RFC5545].

Format

calendarComponent::setProperty( "dtend", dtendDate [, params2 ] )

dtendDate1 = (array) ( "year" => (int) year , "month" => (int) month , "day" => (int) day [, "hour" => (int) hour , "min" => (int) min , "sec" => (int) sec [, "tz" => tz ]] ) dtendDate = (int) year , (int) month , (int) day [, (int) hour , (int) min , (int) sec [, tz ]] dtendDate = array( (int) year , (int) month , (int) day [, (int) hour , (int) min , (int) sec [, tz ]] ) dtendDate = (array) ( "timestamp" => (int) timestamp [,"tz" => tz]) // timestamp without tz will result in a UTC DATE-TIME // timestamp with tz=offset will result in a local DATE-TIME dtendDate = (string) date/datetime string* // Within the "VFREEBUSY" calendar component, // the time MUST be specified in the UTC DATE-TIME tz = (string) <timezone identifier> / offset // timezone will be used as tzidparam (below), if tzidparam not set offset = (int) (+/-)HHmm[ss] // (arr/str) local date + UTC offset // will result in a UTC DATE-TIME params2 = (array) ([ tzidparam/datetimeparam/dateparam ] *[,xparams]) tzidparam = "TZID" => (string) <timezone identifier> // output as local date-time with timezone identifier // if tzidparam="GMT"/"UTC" then // output date-time is suffixed by 'Z' datetimeparam = "VALUE" => "DATE-TIME" // default, output as date-time dateparam = "VALUE" => "DATE" // output as DATE, ex. all-day event xparams = (string) key => (string) value // key prefix "X-"
date/datetime string* recommended formats "20110625", "2011-06-25", "2011/06/26" "20110625051015", "20110625 051015" "20110625T051015", "20110625t051015" "2011-06-25 05:10:15", "2011-06-25T05:10:15", "2011-06-25t05:10:15" "2011/06/25 05:10:15", "2011/06/25T05:10:15", "2011/06/25t05:10:15" trailing characters (digits), if exists, will be interpreted as offset/timezone other string formats, acceptable by PHP strtotime function, may (would) work (notice date restriction)

### 3.2.16 DTSTAMP

The property indicates the date/time the instance of the iCalendar object was created and is OPTIONAL and MUST NOT occur more than once in VEVENT, VTODO, VJOURNAL and VFREEBUSY components. However, DTSTAMP is AUTOMATICALL§Y GENERATED in iCalcreator when creating a component.

DTSTAMP may be required when importing iCal files into some calendar software
(MS etc.), as well as (calendar) x-properties "X-WR-CALNAME", "X-WR-CALDESC" and
"X-WR-TIMEZONE", METHOD property (value PUBLISH etc.) and the (also auto created) UID property.

The value type for DTSTAMP is UTC DATE-TIME.

For methods and formatting, explore the CREATED property.

[index] [top] [up]

### 3.2.17 DTSTART

This property specifies when the calendar component begins. The property is OPTIONAL and MUST NOT occur more than once in VEVENT, VTODO, VJOURNAL and VFREEBUSY components. The property is REQUIRED, but MUST NOT occur more than once in STANDARD and DAYLIGHT components.

The default value type for DTSTART is DATE-TIME, can be set to a DATE value type.

For an "all-day event" and using timeless dates, example (2007-12-01)
DTSTART;VALUE=DATE:20071201
DTEND;VALUE=DATE:20071202. // opt., in effect midnight of the day before the date!!

For methods and formatting, explore the DTEND property.

[index] [top] [up]

### 3.2.18 DUE

This property defines the date and time when a VTODO is expected to be completed and is OPTIONAL and MUST NOT occur more than once and only if DURATION NOT occurs.

The default value type for DUE is DATE-TIME, can be set to a DATE value type.

The value type of the "DTEND" or "DUE" properties MUST match the value type of "DTSTART" property as defined in [RFC5545])

For methods and formatting, explore the DTEND property.

[index] [top] [up]

### 3.2.19 DURATION

The property specifies a positive duration of time.

In a VEVENT
  it is OPTIONAL and MUST NOT occur more than once and MUST NOT occur in pair with DTEND. If one occurs, so MUST NOT the other.
In a VTODO
  it is OPTIONAL and MUST NOT occur more than once and MUST NOT occur in pair with DUE. If one occurs, so MUST NOT the other.
In a VFREEBUSY
  it is OPTIONAL and MUST NOT occur more than once. ([RFC2445])
  it can not appear. ([RFC5545])
In a VALARM
  it is OPTIONAL and MUST NOT occur more than once and MUST occur in pair with TRIGGER. If one occurs, so MUST the other.

If any hour/minute/second duration part is set, all parts are included in output (ex. one hour duration: "PT1H0M0S").

##### Create DURATION

If set, returns [RFC5545] formatted string, otherwise FALSE.

Format

calendarComponent::createDuration()

Example

<?php .. . $str = $component->createDuration(); .. .

##### Delete DURATION

Remove DURATION from component.

Format

calendarComponent::deleteProperty( "DURATION" )

Example

calendarComponent::getProperty( "DURATION", FALSE , TRUE )

output = array( "value" => duration1 , "params" => xparams2 )

Example

<?php .. . $duration = $vtodo->getProperty( "duration" ); .. .

option

If a 4th argument is used and set to TRUE, returned output is in a DATE-TIME output format (like DTEND / DUE), based on DTSTART value with the added DURATION value.

##### Set DURATION

Insert property value.

Format

calendarComponent::setProperty( "duration", duration [, xparams ] )

duration1 = (array) ( "week" => (int) week ) duration1 = array ( "day" => (int) day ) [, "hour" => (int) hour , "min" => (int) min , "sec" => (int) sec ]) duration = (array) ( "sec" => (int) sec ) duration = (array) ( (int) week/false [, (int) day/false [, (int) hour , (int) min , (int) sec ]] ) duration = (int) week/false [, (int) day/false [, (int) hour , (int) min , (int) sec ]] duration = (string) dur-value = ["+"] "P" (dur-date/dur-time/dur-week) dur-date = dur-day [dur-time] dur-time = "T" (dur-hour / dur-minute / dur-second) dur-week = 1*DIGIT "W" dur-hour = 1*DIGIT "H" [dur-minute] dur-minute = 1*DIGIT "M" [dur-second] dur-second = 1*DIGIT "S" dur-day = 1*DIGIT "D" xparams2 = (array) ( *[ (string) key => (string) value ] ) // key prefix "X-"

### 3.2.20 EXDATE

This property defines the list of date/time exceptions for a recurring calendar component and is OPTIONAL and MAY occur more than once in VEVENT, VTODO, VJOURNAL components.

The default value type for EXDATE is DATE-TIME, can be set to a DATE value type.

##### Create EXDATE

If set, returns [RFC5545] formatted string, otherwise FALSE.

Format

calendarComponent::createExdate()

Example

<?php .. . $str = $component->createExdate(); .. .

##### Delete EXDATE

Remove EXDATE from component.

Format

calendarComponent::deleteProperty( "EXDATE" )

Example 1

<?php .. . $vtodo->deleteProperty( "EXDATE" ); .. .

Example 2

Delete EXDATE property no 2.

<?php .. . $vjournal->deleteProperty( "EXDATE", 2 ); .. .

Example 3

Deleting all EXDATE properties.

<?php .. . while( $vjournal->deleteProperty( "EXDATE" )) continue; .. .

##### Get EXDATE

If set, returns property value, otherwise FALSE.

Format 1

calendarComponent::getProperty( "EXDATE" )

output = exdates1

Format 2

calendarComponent::getProperty( "exdate", propOrderNo/FALSE, TRUE )

propOrderNo = (int) specific property value

output = array( "value" => exdates1 , "params" => xparams2 )

Format 3

calendarComponent::getProperty( "EXDATE", propOrderNo )

propOrderNo = (int) specific property value

Get propOrderNo EXDATE

Example

<?php .. . $exdate = $vtodo->getProperty( "exdate" ); .. .

##### Set EXDATE

Insert property value.

The value type for EXDATE should match the DTSTART value type.

If DATE value type is set in params ("VALUE" = "DATE"), all timezone or offset in dates are ignored.
If no "VALUE" value type is set or if DATE-TIME value type or TZID value is set in params, DATE-TIME (default) value type is set.

If "TZID" is set in params, all timezone or offset in dates are ignored (note timestamp, below) and DATE-TIME value type is set.
If empty params and offset in 1st date, all remaining (non-timestamp) dates are set to UTC.
If no "TZID" is set in params and timezone in 1st date, all remaining dates are within this timezone and param "TZID" is set.
If none of the above rules are applicable, DATE-TIME and local date is set default.

Notice, use function transformDateTime to convert a datetime from one time zone to another.

EXDATEs are automatically sorted in ascending order (Y-m-d[-H-i-s]).

In spite of the fact that EXDATE may contain a (comma separated) list of values, a strong recommendation is to split a EXDATE "list" into multiple single EXDATE entries.

Parameters, if any, will be ordered as prescribed in [RFC5545].

Format

calendarComponent::setProperty( "exdate", exdates [, params [, propOrderNo ]] )

exdates1 = (array) ( date *[, date ] ) date = array( (int) year , (int) month , (int) day [, (int) hour , (int) min , (int) sec [, tz ]] ) date1 = (array) ( "year" => (int) year , "month" => (int) month , "day" => (int) day [, "hour" => (int) hour , "min" => (int) min , "sec" => (int) sec [, "tz" => tz ]] ) date = (array) ( "timestamp" => (int) timestamp [, "tz" => tz]) // timestamp without tz will result in a UTC DATE-TIME date = (string) date/datetime string* tz = (string) <timezone identifier> / offset // timezone will be used as tzidparam (below), if tzidparam not set offset = (int) (+/-)HHmm[ss] // (arr/str) local date + UTC offset will result in a UTC DATE-TIME params2 = (array) ([(datetimeparam/dateparam) / tzidparam] *[,xparams]) datetimeparam = "VALUE" => "DATE-TIME" // default, output as date-time dateparam = "VALUE" => "DATE" // output as DATE tzidparam = "TZID" => (string) <timezone identifier> xparams = (string) key => (string) value // key prefix "X-" propOrderNo = (int) order number // 1=1st, 2=2nd etc

##### Set RDATE

Insert property value.

The value type for RDATE should match the DTSTART value type.

If DATE value type is set in params ("VALUE" = "DATE"), all timezone or offset in dates are ignored.
If no "VALUE" value type is set or if DATE-TIME value type or TZID value is set in params, DATE-TIME (default) value type is set.

If "TZID" is set in params, all timezone or offset in dates are ignored (note timestamp, below) and DATE-TIME value type is set.
If empty params and offset in 1st date, all remaining (non-timestamp) dates are set to UTC.
If no "TZID" is set in params and timezone in 1st date, all remaining dates are within this timezone and param "TZID" is set.
If none of the above rules are applicable, DATE-TIME and local date is set default.

Notice, use function transformDateTime to convert a datetime from one time zone to another.

RDATEs are automatically sorted in ascending order (Y-m-d[-H-i-s]).

In spite of the fact that RDATE may contain a (comma separated) list of values, a strong recommendation is to split a RDATE "list" into multiple single RDATE entries.

Parameters, if any, will be ordered as prescribed in [RFC5545].

Format

calendarComponent::setProperty( "rdate", dates [, params [, propOrderNo ]] )

date/datetime string* recommended formats "20110625", "2011-06-25", "2011/06/26" "20110625051015", "20110625 051015" "20110625T051015", "20110625t051015" "2011-06-25 05:10:15", "2011-06-25T05:10:15", "2011-06-25t05:10:15" "2011/06/25 05:10:15", "2011/06/25T05:10:15", "2011/06/25t05:10:15" trailing characters (digits), if exists, will be interpreted as offset/timezone other string formats, acceptable by PHP strtotime function, may (would) work (notice date restriction)

Example

See rules in detail in RFC2445 - Internet Calendaring and Scheduling Core Object Specification (iCalendar).

<?php .. . // $rdate1 = array ( 2001, 1, 1, 1, 1, 1 ); // alt. $rdate1 = array( "year" => 2001 , "month" => 1 , "day" => 1 , "hour" => 1 , "min" => 1 , "sec" => 1 , "tz" => "GMT" ); $rdate2 = array( 2002, 2, 2, 2, 2, 2, "GMT" ); $rdate3 = "3 March 2003 03.03.03"; $rdate4 = array( 2004, 4, 4, 4, 4, 4, "GMT" ); $rdate5 = array( 2005, 10, 5, 5, 5, 5 ); $rdate8 = array( "year" => 2007, "month" => 7, "day" => 7 ); $rdur6 = array( "week" => 0 , "day" => 0 , "hour" => 5 , "min" => 5 , "sec" => 5 ); $rdur7 = array( 0, 0, 6 ); // duration for 6 hours $rdur8 = array( "week" => 8 ); // duration for 8 weeks $vevent = & $vcalendar->newComponent( "vevent" ); $vevent->setProperty( "rdate", array( $rdate1 )); // one recurrence date, date in 7-params format (DATE-TIME) $vevent->setProperty( "rdate", array( $rdate1, $rdate2 )); // two dates, date 7-params format (DATE-TIME) $vevent->setProperty( "rdate", array( array( $rdate1, $rdate2 ) , array( $rdate3, $rdate4 )) , array( "VALUE" => "PERIOD" )); // Both fromdate and enddate must have 7 params (DATE-TIME) !!! $vevent->setProperty( "rdate", array( array( $rdate2, $rdur6 )) , array( "VALUE" => "PERIOD" )); // one duration (fromdate-duration) $vevent->setProperty( "rdate", array( array( $rdate1, $date2 ) , array( $rdate3, $rdur7 )) , array( "VALUE" => "PERIOD" )); // period, pairs of fromdate+enddate and fromdate-duration $vevent->setProperty( "rdate", array( $rdate5, $date8 )) , array( "VALUE" => "DATE" )); // dates in DATE format .. .

### 3.2.36 SEQUENCE

This property defines the revision sequence number of the calendar component within a sequence of revisions. The property is OPTIONAL and MUST NOT occur more than once in VEVENT, VTODO and VJOURNAL components.

It is monotonically incremented by the ORGANIZER's CUA (Calendar User Agent) each time the ORGANIZER makes a significant revision to the calendar component.
When the ORGANIZER makes changes to one of the following properties, the sequence number MUST be incremented: DTSTART, DTEND, DUE, RDATE, RRULE, EXDATE, EXRULE, STATUS. In addition, changes made by the ORGANIZER to other properties can also force the sequence number to be incremented. The ORGANIZER CUA MUST increment the sequence number when ever it makes changes to properties in the calendar component that the ORGANIZER deems will jeopardize the validity of the participation status of the Attendees. For example, changing the location of a meeting from one locale to another distant locale could effectively impact the participation status of the Attendees.

The value type of SEQUENCE is INTEGER.

### 3.2.46 UID

The persistent, globally Unique IDentifier for the calendar component. The property is OPTIONAL and MUST NOT occur more than once in VEVENT, VTODO, VJOURNAL and VFREEBUSY components.
However, UID is AUTOMATICALLY generated in iCalcreator and configuration unique_id is used when auto-creating component UID.

UID generated format :

date("Ymd\THisT")."-".[microSec][random]."@".unique_id

microSec = microseconds, 4 pos
random = 6 characters aA-zZ, 0-9

Example

"20070803T194810CEST-0123U3PXiX@kigkonsult.se"

UID may be required when importing iCal files into some calendar software (MS etc.), as well as (calendar) properties x-properties "X-WR-CALNAME", "X-WR-CALDESC" and "X-WR-TIMEZONE", METHOD (value PUBLISH etc.) and the (also automatically created) DTSTAMP property.

The value type for UID is TEXT.

##### Create UID

If set, returns [RFC5545] formatted string, otherwise FALSE.

Format

calendarComponent::createUid()

Example

<?php .. . $str = $component->createUid(); .. .

##### Delete UID

If UID is remove from a component, UID will automatically be recreated when iCalcreator object output methods like createCalendar, returnCalendar or saveCalendar is executed.

Format

calendarComponent::deleteProperty( "UID" )

Example

<?php .. . $vevent->deleteProperty( "UID" ); .. .

##### Get UID

If set, returns property, otherwise FALSE.

Format 1

calendarComponent::getProperty( "UID" )

output = uid1

Format 2

calendarComponent::getProperty( "UID", FALSE , TRUE )

output = array( "value" => uid1 , "params" => xparams2 )

Example

<?php .. . $uid = $vevent->getProperty( "UID" ); .. .

##### Set UID

Insert property value, overrides any previously set or auto-created UID.

Do NOT use an integer UID or only a component name in UID (ex. "vevent"), this may cause malfunction in iCalcreator object method setComponent with index or UID argument.

Format

calendarComponent::setProperty( "uid", uid [, xparams ] )

uid1 = (string) Value type TEXT xparams2 = array( *[ (string) key => (string) value ] ) // key prefix "X-"

Example

<?php .. . $vevent->setProperty("uid","20070803T194810CEST-0123U3PXiX@kigkonsult.se"); .. .

BUT, due to poorly created iCal media files, a digit UID is accepted in the setProperty( UID ) and parse() methods. Do check for component digit UIDs and remove it (will force a (auto) UID recreation) or (re-)set it manually.

<?php .. . if( ctype_digit( $vevent->getProperty( "UID" ))) $vevent->deleteProperty( "UID" ); .. .

# 4 iCalUtilityFunctions

iCalUtilityFunctions class contains static functions used by iCalcreator, also usable outside the iCalcreator class.

"External" functions
  4.1 convEolChar
  4.2 createTimezone
  4.3 ms2phpTZ
  4.4 transformDateTime
"Internal" functions
  4.5 Misc. date/duration/timestamp util. functions

#### 4.1 convEolChar

Removes any line-endings that may include spaces or tabs (\t) and convert all line endings (iCal default "\r\n"), takes care of "\r\n", "\r" and "\n" and mixed "\r\n"+"\r", "\r\n"+"\n".

Returns string with controlled and corrected line endings.

Format

iCalUtilityFunctions::convEolChar( str, nl )

str = (string) string to adjust nl = line ending to convert to

[index] [top] [up]

#### 4.2 createTimezone

The function, applied on a iCalcrator object instance and using a PHP valid timezone (as argument) creates vtimezone, standard and daylight components, based on PHP DateTimeZone class and the time zone transition dates. (PHP 5 >= 5.2.0)

Recommendation is to call the function after editing components (and without (period) from/to arguments, below), it will automatically create timezone components to fit.

If no time zone transition exists within date arguments or within the "DTSTART"s span, then the time zone transition with the highest transistion date before "from" date is used as base. If still missing,a timezone standard component are created, using current date.

Note, only when timezone NOT is UTC. For dates with UTC DATE-TIME, read this!

FALSE is returned if not using a PHP valid timezone.

Format

iCalUtilityFunctions::createTimezone( calendar, timezone [, xprops, [, from [, to ]]] )

calendar = (object) iCalcreator instance timezone = (string) an PHP (DateTimeZone) valid timezone xprops = (array) ( *[ x-propName => value ] ), timezone non-standard properties from = (int) timestamp, period start date to = (int) timestamp, period end date if the "from" and "to" arguments are missing, the calendar getProperty method (with "DTSTART" as argument) is used to get the lowest (modified, minus one month) and highest (modified, plus one year) DTSTART dates.

Example

<?php .. . $tz = "Europe/Stockholm"; $config = array( "unique_id" => "kigkonsult.se", "TZID" => $tz ); $c = new vcalendar( $config ); $c->setProperty( "X-WR-TIMEZONE", $tz ); .. . .. . // insert components or parse an iCal file .. . $xprops = array( "X-LIC-LOCATION" => $tz ); iCalUtilityFunctions::createTimezone( $c, $tz, $xprops ); .. .

Output example (when using iCalcreator object createCalendar or returnCalendar methods):

BEGIN:VTIMEZONE TZID:Europe/Stockholm X-LIC-LOCATION:Europe/Stockholm BEGIN:STANDARD DTSTART:20111030T003000 TZOFFSETFROM:+0200 TZOFFSETTO:+0100 TZNAME:CET END:STANDARD BEGIN:DAYLIGHT DTSTART:20110327T002000 TZOFFSETFROM:+0100 TZOFFSETTO:+0200 TZNAME:CEST END:DAYLIGHT END:VTIMEZONE

[index] [top] [up]

#### 4.3 ms2phpTZ

Conversion (very simple) of a MS timezone to a PHP5 valid (Date-)timezone,
matching (MS) UTC offset and time zone descriptors, based on PHP DateTimeZone class. (PHP 5 >= 5.2.0)

If TRUE is returned, the MS timezone argument (below) is converted to a PHP5 time zone, otherwise unaltered.

Format

iCalUtilityFunctions::ms2phpTZ( timezone )

timezone = (string) MS timezone (input), PHP5 timezone (output)

Example

<?php .. . $search = '"(UTC-06:00) Central Time (US & Canada)"'; echo "MS tz:'$search'<br>\n"; if( FALSE !== iCalUtilityFunctions::ms2phpTZ( $search )) echo "PHP tz:'$search'<br>\n"; .. .

[index] [top] [up]

#### 4.4 transformDateTime

Transforms a datetime from a time zone to another. (Requires PHP >= 5.2.0 and PHP DateTimeZone acceptable time zones).

FALSE is returned if not using a "strtotime" acceptable datetime string or unacceptable PHP time zones. If TRUE, the dateTime argument (below) is converted to the new time zone, otherwise unaltered.

A DATE input (<year><month><day>) will be expanded to a DATETIME (<year><month><day>000000) before transform.

Format

iCalUtilityFunctions::transformDateTime( dateTime, timezoneFrom [, timezoneTo [, format ]] )

dateTime = (array) ( "year" => (int) year // input , "month" => (int) month , "day" => (int) day [, "hour" => (int) hour , "min" => (int) min , "sec" => (int) sec ] ) dateTime = (array) ( (int) year // input , (int) month , (int) day [, (int) hour , (int) min , (int) sec ] ) dateTime = (array) ( "timestamp" => (int) timestamp ) // input dateTime = (string) datetime string* // input dateTime = (string) datetime string // on successful output timezoneFrom = (string) a PHP (DateTimeZone) valid time zone timezoneTo = (string) a PHP (DateTimeZone) valid time zone, default "UTC" format = (string) output format (any date formatting, default "Ymd\THis")
datetime string* recommended formats "20110625", "2011-06-25", "2011/06/26" "20110625051015", "20110625 051015" "20110625T051015", "20110625t051015" "2011-06-25 05:10:15", "2011-06-25T05:10:15", "2011-06-25t05:10:15" "2011/06/25 05:10:15", "2011/06/25T05:10:15", "2011/06/25t05:10:15" other string formats, acceptable by PHP strtotime function, may (would) work (notice date restriction)

Example

Convert from time zone "Europe/Stockholm" to "UTC"

<?php .. . $d = date( "Y-m-d H:i:s" ); $tzFr = "Europe/Stockholm"; if( FALSE !== iCalUtilityFunctions::transformDateTime( $d, $tzFr )) $event->setProperty( "dtstart", $d."Z" ); else $event->setProperty( "dtstart", $d, array( "TZID" => $tzFr )); .. .
