PHP based Ajax chat / support / assistance script

Question

I have been assigned a task in a field I don't know anything about: Live chat directly on a PHP based web site. One-on-one only (Visitor to admin), with the possibility for both parties to store the conversation as text (though I could add that if necessary). Full fledged conversation management (continue conversation etc.) would be a plus but are not required.

It should be simple to use, easy to customize via CSS, AJAXy and not too heavy on the server. Open Source would be a big plus as I'm going to have customize it intensely.

Answer 1

This one is pretty easy to get rolling.

Answer 2

A little aged, but might provide a good foundation to build up from:

SourceForge / PHP Help Agent

Help Agent is a web site support program. It includes Knowledge Base, Trouble Ticket and Live Chat. It allows easy administration and the ability to add support personnel and includes a visual online/offline indicator that can be dislayed on your pages.

Answer 3

I'd suggest using jquery to make implementing the ajax easy.
