PHP + AJAX Chat

June 25, 2009

I've written a minimalistic, proof-of-concept AJAX chat in PHP. If anyone is interested in a basis for further development, see this.

The only funny part in coding this was finding out that PHP sessions are mutually exclusive (and such, if a client is AJAX-waiting for a PHP script which is delaying on purpose, the session can't be accessed from another script. You need to close the session in the delaying PHP script).
