iCalcreator is a PHP class managing iCal formatted files for non-calendar systems like CMS, project management systems and other applications able to process calendar information like agendas, tasks, reports, totos, journaling data and for communication with calendar systems and applications.
This is a short summary how to use iCalcreator; create, parse, edit, select and output functionality.
iCalcreator is built of a single class file with a simple interface and are calendar component property oriented. Development environment is PHP version 5.x but coding is done to meet 4.x backward compability.

#### iCal

A short iCal description is found at Wikipedia . If You are not familiar with iCal, read this first!
Knowledge of calendar protocol rfc2445/rfc2446 is to recommend;
rfc2445 - Internet Calendaring and Scheduling Core Object Specification (iCalendar)
rfc2446 - iCalendar Transport-Independent Interoperability Protocol (iTIP) Scheduling Events, BusyTime, To-dos and Journal Entries
All functions calls are made as simple as possible BUT (, !!!,) read these rfc's properly!
