# 1 INTRO

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

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

For iCalcreator 2.39 version (and later), PHP version >= 7.0 is required. v2.29.25 and later asserts PHP 7+ compability using PHPCompatibility and (v2.39+) PHPStan.

## 1.1 Standards

#### iCal

A short iCal description is found at Wikipedia. If You are not familiar with iCal, read this first!

The iCalendar format, iCal, are 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.

rfc6321
  xCal: The XML Format for iCalendar
rfc7986
  New Properties for iCalendar

rfc5545 and rfc5546 obsoletes, respectively, rfc2445 and rfc2446.

A short xCal description is found at Wikipedia.

## 1.8 Additional descriptors

Some properties (ex. as described in wikipedia:iCal) may be required when importing iCal formatted data into some calendaring software (MS etc). Also X-properties may appear in exports. Below are examples

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 *
  UID *
on component level in a vtimezone component
  X-LIC-LOCATION x-property

* Created automatically in iCalcreator, if not set.

To ease up usage, constants
- Kigkonsult\Icalcreator\Vcalendar::METHOD,
- Kigkonsult\Icalcreator\Vcalendar::X_WR_CALNAME,
- Kigkonsult\Icalcreator\Vcalendar::X_WR_CALDESC,
- Kigkonsult\Icalcreator\Vcalendar::X_WR_RELCALID,
- Kigkonsult\Icalcreator\Vcalendar::X_WR_TIMEZONE,
- Kigkonsult\Icalcreator\Vcalendar::X_LIC_LOCATION
are available.

Example

A strong recommendation is also to set config unique_id when creating a new Vcalendar instance, to ensure accurate setting of PRODID property. Also setting "X-WR-TIMEZONE" (below) is to recommend.

use Kigkonsult\Icalcreator\Vcalendar; $vcalendar = new Vcalendar( [ Vcalendar::UNIQUE_ID => "kigkonsult.se" ] ); $vcalendar->setMethod( Vcalendar::PUBLISH ) ->setXprop( Vcalendar::X_WR_CALNAME, "Calendar Sample" ) ->setXprop( Vcalendar::X_WR_CALDESC, "Calendar Description" ) ->setXProp( Vcalendar::X_WR_RELCALID, "3E26604A-50F4-4449-8B3E-E4F4932D05B5" ) ->setXprop( Vcalendar::X_WR_TIMEZONE, "Europe/Stockholm" );

If not set, the DTSTAMP and UID properties are automatically created by iCalcreator
for vcalendar (UID only), vevent, vtodo, vjournal and vfreebusy components
when using Vcalendar method returnCalendar
or using component::getDtstamp() (DTSTAMP) or component::getUid() (UID) methods.

# 3 methods

## 3.1 Vcalendar methods

### 3.1.1 Constructors

#### 3.1.1.1 Vcalendar

Create a new VCALENDAR object instance.

##### Constructor

Throws InvalidArgumentException on (set)config error.

Format

Vcalendar::__construct( [ config ] )

The calendar PRODID property (based on the configuration unique_id) and the calendar/component UID property are AUTOMATICALLY generated in iCalcreator.

Example 2

use Kigkonsult\Icalcreator\Vcalendar; $tz = "Europe/Stockholm" $vcalendar = new Vcalendar( [ Vcalendar::UNIQUE_ID => "kigkonsult.se" ] ); $vcalendar->setXProp( Vcalendar::X_WR_TIMEZONE, $tz ); // insert components or parse an iCal string calendar (and edit components) .. .

Some calendar software may also require calendar property X-WR-TIMEZONE and vtimezone component with property X-LIC-LOCATION, review Vcalendar populate or Util/VtimezonePopulateFactory::process methods.

##### factory

Create a new Vcalendar object instance using a factory-method.

Throws InvalidArgumentException on (set)config error.

#### 3.1.3.3 replaceComponent

Replace calendar component in vcalendar based on component property UID (EVENT / VTODO / VJOURNAL / VFREEBUSY). If not found, inserted last in component chain.

In case of multiple components sharing the same UID (ex. a RECURRENCE-ID property altering a recurrence pattern), the first found is replaced and it may lead to unpredictable result, to use with care.

For a VTIMEZONE component, a TZID match is required.

A successfull replace returns bool true otherwise bool false.

Throws InvalidArgumentException/UnexpectedValueException on unknown or not-found component error.

Format

Vcalendar::replaceComponent( component )

component = (object) component instance

Example

$vcalendar->replaceComponent( $component );

[index] [top] [up]

#### 3.1.3.4 selectComponents

Format 1

Selects EVENT / VTODO / VJOURNAL / VFREEBUSY components from the Vcalendar instance on based on dates (notice date restraints), based on the initial DTSTART property along with the RRULE, RDATE, EXDATE and EXRULE properties in the component and UID-matched component(s) with RECURRENCE-ID.

Requirement:

- The property DTSTART is required. If missing in a VTODO component, DUE is used.
- If not using local date, timezone in property DTSTART etc. MUST be PHP compliant.

Limitations:

- The values "SECONDLY" / "MINUTELY" / "HOURLY" in the "FREQ" rule part are NOT supported.
- If using components with properties
  UID in combination with SEQUENCE and RECURRENCE-ID
  (i.e. altering an individual instance within the recurrence set),
  the RECURRENCE-ID parameter "RANGE" ("THISANDPRIOR" / "THISANDFUTURE") is NOT (yet) supported.
- only one reccurrence a day
- a RDATE reccurrence will overwrite any RRULE reccurrence, on an date (Ymd) basis
- no X-CURRENT-DTEND if no DTEND (DUE) is set (below)

Returns an array with components (events) or bool false is returned if no found component(s) exists. Replacing (RECURRENCE-ID) components has (if missing) updated COMMENT, DESCRIPTION and COMMENTs properties.

Added X-properties in recurrent instances of a calendar component:

- "X-CURRENT-DTSTART", TEXT content, "Y-m-d [H:i:s [timezone]]" showing the current start date.
- "X-CURRENT-DTEND" alt. "X-CURRENT-DUE" (opt), TEXT content, "Y-m-d [H:i:s [timezone]]" showing the current end date.
- "X-RECURRENCE", the RRULE/RDATE recurrence pattarn number (not in the recurrence start), also after an RECURRENCE-ID change
- "X-OCCURENCE", contains, where applicable, single multi-day recurrence event day number (formatted as 'day X of Y')

To ease up usage, constants
- Kigkonsult\Icalcreator\Vcalendar::X_CURRENT_DTSTART,
- Kigkonsult\Icalcreator\Vcalendar::X_CURRENT_DTEND,
- Kigkonsult\Icalcreator\Vcalendar::X_CURRENT_DUE,
- Kigkonsult\Icalcreator\Vcalendar::X_RECURRENCE,
- Kigkonsult\Icalcreator\Vcalendar::X_OCCURENCE
are available.

#### 3.1.3.5 setComponent

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

A successful update returns true.

The method throws InvalidArgumentException on unknown component.

format 1

Insert last in component chain.

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

component = (object) Vcalendar 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) Vcalendar 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) Vcalendar 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) Vcalendar component instance

Example

use Kigkonsult\Icalcreator\Vcalendar; $vcalendar = new Vcalendar( [ Vcalendar::UNIQUE_ID => "kigkonsult.se" ] ); $iCalContent = file_get_contents( "calendar.ics" ); $vcalendar->parse( $iCalContent ); $vevent = vcalendar->getComponent( 1 ); // fetch first EVENT $vevent->setDtstart( new DateTime( "2006-12-24 19:30:00" ) ); // update DTSTART property $vcalendar->setComponent( $vevent, 1 ); // replace first component

### 3.1.4 Vcalendar calendar methods

#### 3.1.4.1 parse and merge

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

If missing, component property UID is created when parsing.

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.

Throws InvalidArgumentException on argument error, UnexpectedValueException on parse error.
Note, parsing an empty calendar (ie without EVENTs etc) will NOT lead to error. To count components, before and after parse, use countComponents method.

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

For parsing an internet URL resource, UrlRsrc can be used.

Format

The method returns the class instance (static).

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

use Kigkonsult\Icalcreator\Vcalendar; // set Your unique id, // site info for the Vcalendar PRODID property $vcalendar = new Vcalendar( [ Vcalendar::UNIQUE_ID => "kigkonsult.se", ] ); // get iCal contents from file $iCalContent = file_get_contents( "calendar.ics" ); // parse iCal contents $vcalendar->parse( $iCalContent );

parse example 2

PHP file_get_contents may work on external resources.

use Kigkonsult\Icalcreator\Vcalendar; // set Your unique id, // site info for the Vcalendar PRODID property $vcalendar = new Vcalendar( [ Vcalendar::UNIQUE_ID => "kigkonsult.se" ] ); // get iCal contents from external resource $iCalContent = file_get_contents( "http://www.ical.net/calendars/calendar.ics" ); // parse iCal contents $vcalendar->parse( $iCalContent );

parse example 3

Here using UrlRsrc to download an internet (URL) resource.

use Kigkonsult\Icalcreator\Vcalendar; use Kigkonsult\Http\UrlRsrc; // set Your unique id, // site info for the Vcalendar PRODID property $vcalendar = new Vcalendar( [ Vcalendar::UNIQUE_ID => "kigkonsult.se" ] ); // get iCal contents from external resource $iCalContent = UrlRsrc::getContent( "http://www.ical.net/calendars/calendar.ics" ); // parse iCal contents $vcalendar->parse( $iCalContent );

parse example 4

Parse an array with iCal formatted rows.

use Kigkonsult\Icalcreator\Vcalendar; $vcalendar = new Vcalendar( [ Vcalendar::UNIQUE_ID => "kigkonsult.se" ] ); $str = [ "BEGIN:VCALENDAR", "PRODID:-//kigkonsult.se//NONSGML kigkonsult.se iCalcreator 2.39//", "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 );

merge example

Parse two iCal files into one.

use Kigkonsult\Icalcreator\Vcalendar; $vcalendar = new Vcalendar( [ Vcalendar::UNIQUE_ID => "kigkonsult.se" ] ); $iCalContent = file_get_contents( "file1.ics" ); $vcalendar->parse( $iCalContent ); $iCalContent = file_get_contents( "file2.ics" ); $vcalendar->parse( $iCalContent ); file_put_contents( "icalmerge.ics", $vcalendar->createCalendar(), LOCK_EX );

[index] [top] [up]

#### 3.1.4.3 returnCalendar

Redirect the Vcalendar instance content to user browser. Filename, addressed to browser, is automatically generated if missing or not set, the filename will look like it is set using

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

The method do not stop PHP script (exit), returns (bool) true on success.

Format

Vcalendar::returnCalendar( [ utf8Encode [, gzip [, cdType [, fileName ]]]] )

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 cdType = (bool) true: (default) Content-Disposition: attachment false: Content-Disposition: inline fileName = (string) returned file Name

Example 1

use Kigkonsult\Icalcreator\Vcalendar; $vcalendar = new Vcalendar( [ Vcalendar::UNIQUE_ID => "kigkonsult.se" ] ); $vevent = $vcalendar->newVevent() ->setDtstart( new DateTime( "2007-04-01 19:00:00", new DateTimezone( "Europe/Stockholm" ) ) ) ->setDuration( new DateInterval( "PT1H" )) ->setLocation( "Central Plaza" ) ->setSummary( "PHP summit" ); $vcalendar->returnCalendar(); exit;

Example 2

#### 3.1.4.4 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 Vcalendar 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 using createCalendar method (or returnCalendar).
ALARM sub-components, if exists, are not sorted.

Vcalendar::sort()

Example

use Kigkonsult\Icalcreator\Vcalendar; $vcalendar = new Vcalendar( [ Vcalendar::UNIQUE_ID => "kigkonsult.se" ] ); $iCalContent = file_get_contents( "calendar.ics" ); $vcalendar->parse( $iCalContent ); $vcalendar->sort(); $vcalendar->returnCalendar(); exit;

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) and components without RECURRENCE-ID last.

Note, to ease up usage, you will find convenient constants for component names, properties, config keys etc in (src/)IcalInterface.

## 3.2 Component property methods

All iCalcreator component object property methods for get/set data.
For property format in detail, see RFC5545 - Internet Calendaring and Scheduling Core Object Specification (iCalendar).

### 3.2.1 Date restraints

Notice for properties and VALUE=DATE-TIME in UTC timezone.

RFC5545: 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 timezone.

Due to a limitation in PHP date functions (on 32 bit systems), a date (ex. while setting DTSTART property) before 1970 or after GMT may force a PHP date function to generate an error or set date to "January 1 1970". Timezones need to be PHP complient!

Recommended string date(time) 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" Any trailing characters (digits), if exists, will be interpreted as offset/timezone. Other string formats, acceptable by PHP strtotime function, may work.

[index] [top] [up]

### 3.2.2 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.

Uou can also parse 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. Empty lines in a text property must be replaced by "\n".

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.

Throws InvalidArgumentException, UnexpectedValueException on parse error.

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

Format

calendarComponent::parse( propertyText )

propertyText = (string) [RFC5545] formatted property, (array) [RFC5545] formatted properties, property name must start string / rows(-s) // For a property array MUST all, but first row, be prefixed by space.

example

$e = $vcalendar->newVevent(); $e->parse( "DTSTAMP:19970324T1200Z" ); $e->parse( "SEQUENCE:0" ); $e->parse( "ORGANIZER:MAILTO:jdoe@host1.com" ); $e->parse( [ "ATTENDEE;RSVP=TRUE:MAILTO:jsmith@host1.com", "ATTENDEE;RSVP=TRUE:MAILTO:jsmith@host2.com", "ATTENDEE;RSVP=TRUE:MAILTO:jsmith@host3.com", "ATTENDEE;RSVP=TRUE:MAILTO:jsmith@host4.com" ]); $e->parse( "DTSTART:19970324T123000Z" ); $e->parse( "DTEND:19970324T210000Z" ); $e->parse( "CATEGORIES:MEETING,PROJECT" ); $e->parse( "CLASS:PUBLIC" ); $e->parse( "SUMMARY:Calendaring Interoperability Planning Meeting" ); $e->parse( "STATUS:DRAFT" ); $e->parse( "DESCRIPTION:Project xyz Review Meeting Minutes\\n " .

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

To ease up usage, constants
- Kigkonsult\Icalcreator\Vcalendar::EXDATE
- Kigkonsult\Icalcreator\Vcalendar::VALUE
- Kigkonsult\Icalcreator\Vcalendar::DATE
- Kigkonsult\Icalcreator\Vcalendar::DATE_TIME
are available.

##### Create EXDATE

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

Format

calendarComponent::createExdate()

Example

$str = $component->createExdate();

##### Delete EXDATE

Remove EXDATE from component.

Format

calendarComponent::deleteExdate()

Example 1

$vtodo->deleteExdate();

Example 2

Delete EXDATE property no 2.

$vjournal->deleteExdate( 2 );

Example 3

Deleting all EXDATE properties.

while( $vjournal->deleteExdate()) { continue; }

##### Get EXDATE

If set, returns property value, otherwise bool false.

Format 1

calendarComponent::getExdate()

output = exdates1 (with date1)

Format 2

calendarComponent::getExdate( propOrderNo/null, true )

propOrderNo = (int) specific property value

output = array( "value" => exdates1 (with date1) , "params" => xparams2 )

Example

$exdate = $vtodo->getExdate();

##### Set EXDATE

Set property value.

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

If no "VALUE" value type is set, DATE-TIME (default) value type is set.

If timezone in 1st date, all remaining dates are within this timezone and param "TZID" is set.

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 an EXDATE "list" into multiple single EXDATE entries. (But if you do, don't mix timezones, may result in incorrect date values.)

The method returns the class instance (static).

The method throws InvalidArgumentException on empty value and config ALLOWEMPTY is set to false (default true), Exception on DateTime error.

Parameters will be ordered as prescribed in [RFC5545].

Format

calendarComponent::setExdate( exdates [, params [, propOrderNo ]] )

exdates1 = date / (array) ( date *[, date ] ) date = (object) DateTimeInterface instance date = (string) date/datetime string* params2 = (array) ([(datetimeparam/dateparam) / tzidparam] *[,xparams]) // default, output as date-time datetimeparam = Vcalendar::VALUE => Vcalendar::DATE_TIME // output as DATE dateparam = Vcalendar::VALUE => Vcalendar::DATE tzidparam = Vcalendar::TZID => (string) <timezone identifier> // key prefix "X-" xparams = (string) key => (string) value // 1=1st, 2=2nd etc propOrderNo = (int) order number
* please notice date restraints.

Example

Exclude 2006-08-11 from the recurrence pattern.

use Kigkonsult\Icalcreator\Vcalendar; try { $vevent->setExdate( [ new DateTime( '2006-08-11' ) ], [ Vcalendar::VALUE => Vcalendar::DATE ] ); } catch( Exception $e ) { die( $e->getMessage()); }

Example

$freebusy = $vfreebusy->getFreebusy();

##### Set FREEBUSY

Set property value. FREEBUSY date is always a UTC timezone DATE-TIME in pair with another UTC timezone DATE-TIME or a DateInteval. Set dates within the same timezone, otherwise it may lead to unpredictable result;

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

The method returns the class instance (static).

The method throws InvalidArgumentException on empty value and config ALLOWEMPTY is set to false (default true), Exception on DateTime/DateInterval error.

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.

### 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 when creating component.

Note, as described in rfc7986 iCalendar Property Extensions, UID (may) occur once in VCALENDAR and may NOT be supported by all calendaring software. Calendar UID is automatically generated at instance creation. Usage and examples, below, corresponds to vcalendar usage.

UID is a hex-encoded random Universally Unique Identifier (UUID) value as defined in Sections 4.4 and 4.5 of rfc4122.

Example

UID:5FC53010-1267-4F8E-BC28-1D7AE55A7C99

UID may be required when importing iCal formatted information 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.

To ease up usage, constant Kigkonsult\Icalcreator\Vcalendar::UID is available.

##### Create UID

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

Format

calendarComponent::createUid()

Example

$str = $component->createUid();

##### Delete UID

If UID is remove from a component, UID will automatically be recreated when Vcalendar output methods like createCalendar and returnCalendarare used.

Format

calendarComponent::deleteUid()

Example

$vevent->deleteUid();

##### Get UID

If set, returns property, otherwise bool false.

Format 1

calendarComponent::getUid()

output = uid1

Format 2

calendarComponent::getUid( true )

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

Example

$uid = $vevent->getUid();

##### Set UID

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

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

The method throws InvalidArgumentException on empty (non-zero) value.

Format

calendarComponent::setUid( uid [, xparams ] )

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

Example

$vevent->setUid( "20070803T194810CEST-0123U3PXiX@kigkonsult.se" );

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

if( ctype_digit( $vevent->getUid())) { $vevent->deleteUid(); }

#### 3.4.4 Vtimezone populate

The Util/VtimezonePopulateFactory::process (static) method, applied on a Vcalendar instance, return the Vcalendar instance with Vtimezone, Standard and Daylight components, using on PHP DateTimeZone class and time zone transition (UTC) timestamps. If Vtimezone exists in calendar, it is replaced.

Recommendation is to call the method after editing components (and without (period) from/to arguments).

To ease up usage, constants
- Kigkonsult\Icalcreator\Vcalendar::X_WR_TIMEZONE
- Kigkonsult\Icalcreator\Vcalendar::X_LIC_LOCATION
are available.

Throws Exception on invalid (PHP) timezone.

Format

Vtimezone::populate( calendar, [ timezone [, xprops, [, from [, to ]]]] )

calendar = (object) Vcalendar instance timezone = (string) valid timezone, acceptable by PHP DateTimeZone* xprops = (array) ( *[ x-propName => value ] ), timezone non-standard properties from = DateTimeInterface | (int) timestamp, period start date** to = DateTimeInterface | (int) timestamp, period end date** * If no argument timezone, the argument xProps is searched for "X-WR-TIMEZONE" and "X-LIC-LOCATION" keys. If not found then calendar are searched for the X-properties. If still none found, "UTC" is used. ** If empty "from" and "to" arguments, the calendar components "DTSTART" values are used to get the lowest (modified, minus 12 month) and highest (modified, plus 18 month) dates.

Example

Using the Util/VtimezonePopulateFactory::process (static) method.

use Kigkonsult\Icalcreator\Vcalendar; $calendar = new Vcalendar( [ Vcalendar::UNIQUE_ID => "kigkonsult.se" ] ); $timezone = 'Europe/Stockholm'; .. . // insert components or parse an iCal string .. . $calendar = VtimezonePopulateFactory::process( $calendar, $timezone );

Example 2

Using the shortcut The Vcalendar::vtimezonePopulate() method.

use Kigkonsult\Icalcreator\Vcalendar; $calendar = new Vcalendar( [ Vcalendar::UNIQUE_ID => "kigkonsult.se" ] ); $timezone = 'Europe/Stockholm'; .. . // insert components or parse an iCal string .. . $calendar->VtimezonePopulate( $timezone );

Output example (when using Vcalendar 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

#### 3.4.5 Review timezones, opt alter to PHP timezone

The Vcalendar::parse or component::parse will throw exception when the input data contains PHP unknown timezones, ex MS listed at https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/default-time-zones.

To support other (MS) timezones mapping to PHP timezones (ie timezones with the same or nearby UTC offset), the RegulateTimezoneFactory::process method can be used before parse. The factory review the Vtimezone property TZID and component date properties DTSTART, DTEND, DUE, RECURRENCE-ID, EXDATE and RDATE and parameter "TZID".

The method throws Exception when unknown timezone not can be mapped.

Return rfc5545 formatted calendar string.

Format

RegulateTimezoneFactory::process( iCalData )

iCalData = string|array $iCal strict rfc5545 formatted calendar

use Kigkonsult\Icalcreator\Util\RegulateTimezoneFactory; $iCalStringToParse = RegulateTimezoneFactory::process( $iCalInput );

Any unknown timezone (ex MS "Customized Time Zone"), if used in VTIMEZONE, will map to a PHP timezone (using TZOFFZETTO values) with nearby offsets.

To specify a "direct" map for a PHP unknown timezone, use (in static style format)

RegulateTimezoneFactory::process( icalInput, [ *( <otherTimezone> => <phpTimezone> ) ] )

or (as object oriented style example)

use Kigkonsult\Icalcreator\Util\RegulateTimezoneFactory; $iCalStringToParse = RegulateTimezoneFactory::factory( $iCalInput ) ->addOtherTzPhpRelation( $otherTimezone, $phpTimezone ) ->processCalendar() ->getOutputiCal();

# 4 XML, json and vCard support

### 4.3 iCalcreator and iCalXMLFactory class

The IcalXMLFactory class methods converts iCal into XML and parses XML into iCal. XML is defined by [RFC6321], "xCal: The XML Format for iCalendar".

#### 4.3.1 iCal2XML

The (static) iCal2XML method converts an Vcalendar instance to XML.

The iCal2XML method uses the SimpleXML extension (and "libxml" PHP extension).

An rfc6321 XML string is returned.

Format

IcalXMLFactory::iCal2XML( iCalobj )

iCalobj = (object) Vcalendar instance

$xmlString = Kigkonsult\Icalcreator\Util\IcalXMLFactory::iCal2XML( $vcalendar );

#### 4.3.2 XML2iCal

The (static) method accepts a well-formed (rfc6321) XML string as argument.

On success, an Vcalendar instance is returned, on error false.

Format

IcalXMLFactory::XML2iCal( xmlstr [, config] )

xmlstr = (string) rfc6321 XML config = (array) iCalcreator config array (opt)

### 4.5 iCalcreator and iCalvCardFactory class

The Kigkonsult\Icalcreator\Util\IcalvCardFactory class has two methods to produce vCard string output.

#### 4.5.1 iCal2vCard

The (static) method converts a single email (iCal "cal-address") into (string) vCard.

Returns vCard string.

Format

IcalvCard::iCal2vCard( email [, version ] )

email = (string) email, ATTENDEE, ORGANIZER and opt CONTACT "cal-address" version = (string) vCard version, "2.1" (default), "3.0", "4.0"

[index] [top] [up]

#### 4.5.2 iCal2vCards

The (static) method collects and converts all ATTENDEEs and ORGANIZERs values (iCal "cal-address") and CONTACTs into simplified vCard (string) output using

- iCalvCardFactory::iCal2vCard, above
- Kigkonsult\Icalcreator\Util\CalAddressFactory::getCalAdresses( vcalendar [, properties [, inclParams ]] )
  - vcalendar = (object) Vcalendar instance
  - properties = array, default [ATTENDEE, ORGANIZER, CONTACT]
  - inclParams = (bool) default true: search property values and parameters, false: values only

Format

IcalvCard::iCal2vCards( vcalendar [, version [, inclParams [, count ]]] )

vcalendar = (object) Vcalendar instance version = (string) vCard version, "2.1" (default), "3.0", "4.0" inclParams = (bool) default true: search property values and parameters, false: values only count = (int) number of vCards in output

Return vCard(s) string.
