This is a package of classes that are meant to provide an interface to access data of iCalendar and vCard files defined by the IMC (Internet Mail Consortium).

The library can read and write files with the formats defined by IMC.

PHP 4.x Based vCard Reader/Writer Class by Andreas Haberstroh Ever since I discovered the Internet Mail Consortium website ( and learned about vCard and iCalendar files, I've been waiting for a PHP library that could both read and write these file formats, along with allowing access to the components and properties in a functional manner. Unfortunately, many attempts that have popped up on the Internet fall short of usefulness for me. Most classes that I've seen require direct access to internal class variables. This requires intense knowledge of the format for vCard and iCalendar. I'm a firm believer in encapsulation. So, I cracked open the latest RFC's on vCard and iCalendar formats and decided, it's time to roll my own. My class library borrowed from a few of the libraries I found. Mostly, I borrowed the parameter parsing code. I used stuff from File_IMC on PEAR, written by Marshall Roch <> and Paul Jones <>. I've also borrowed code from the vCard PHP project <>, written by Frank Hellwig <>. These classes are broken into the following hierarchical tree: imcComponent imc_vCard imcProperty imcPropertyAdr imcPropertyN imcProperties live inside a imcComponent. The base imcComponent class can also parse iCalendar files. I'm currently working on a library to deal with iCalendar files. I've included a simple example application called test_vcard.php. This shows using the vCard object as a stand alone object, and also parses a simple vcf file and displays the results. For a full blown usage sample, I'd suggest visiting This sample allows for reading and writing to an addressbook. Storing more than 50 names in the address book can cause problems, in that the webserver needs to read and parse the contents of the entire file, even when paging. A better solution would be to store the data in a database.

This package really does not work properly.
