One of my recent projects needed to have a chat facility built in that works between staff and clients. I wanted to build an Ajax chat system and thought rather than re-inventing the wheel, I would look for someone else’s solution to an Ajax based chat system. I came across this website by Cristian Darie. I had read through some of Cristian’s scripts and articles in the past so I knew that he wrote quality code and made quality systems. His book about PHP and SEO is well worth a read.
I found lots of other examples of Ajax based chat but most of them were dirty, buggy, and smelly. So I heavily modified Cristian’s code to suit my needs and used it in the project. Thanks Cristian!
