<a name="INTRO"></a><h1>1 INTRO</h1>
<p>
iCalcreator is a <em>PHP</em> class package managing iCal files, supporting (non-)<strong>calendar</strong>
systems and applications to process and communicate <strong>calendar</strong> information like
events, agendas, tasks, reports, totos and journaling information.
</p>
<p>
The iCal standards are <a href="#Standards">rfc5545/rfc5546 (rfc2445/rfc2446)</a>.</p>
<p>
iCalcreator features create, parse, edit and select <strong>calendar</strong> and <strong>calendar</strong> components.
</p>
<p>
The iCalcreator package, built of a <strong>calendar</strong> class with support of a function class and helper functions,
are <strong>calendar</strong> component property oriented. For iCalcreator 2.18 version (and later),
<em>PHP</em> version >= 5.2.0 is required, due to the use of <em>PHP</em> DateTime class (and related functions) .
</p>
<p>
The iCalcreator main class, utility class and helper functions are all included in the "iCalcreator.class.php" file.
</p>
<p>
More iCalcreator supplementary, "howto" and coding support information will be found at

A strong recommendation is to have this document open in parallell when exploiting the link.

A short iCal description is found at <a href="http://en.wikipedia.org/wiki/ICalendar#Core_object" title="iCalendar From Wikipedia, the free encyclopedia" target="_blank">Wikipedia</a>. If You are not familiar with iCal, read this first!
Knowledge of <strong>calendar</strong> protocol rfc5545/rfc5546 is to recommend.
</p>
<p>
Any references to rfc2445, below, corresponds to rfc5545.

<h4>xCal</h4>
<p>iCalcreator also supports xCal (iCal xml) rfc6321, "xCal: The XML Format for <strong>iCalendar</strong>", to be downloaded from</p>

<p>
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.

A strong recommendation is also to set config <a href="#Unique_id">unique_id</a>, creating a new vcalendar/component instance,
to ensure accurate setting of all components <a href="#UID">UID</a> property, especially before <a href="#parse_merge">parse</a>.
Also setting of config timezone ("TZID" and "X-WR-TIMEZONE" below) is to recommend.
</p>
<p class="example"><?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";
