Free jQuery/PHP Powered Chat Room, Fully jQuery/JavaScript.

we are going to build a little chat program that is really easy to get up and running on any server running PHP. No database is required – as the chat will store itself in a simple text file.

The technologies used:

• PHP – Will handle all the server side stuff
  • Writing new messages to the text file
  • Reading out new messages from the text file
  • Retrieving the “state” of the text file
  • Basic security
• jQuery/JavaScript – Will handle the client side stuff. This is an AJAX-y application, meaning that messages pop onto the screen (both yours and others) without needing any page refresh.
  • Periodically asking the server if there are new messages that have been posted
  • Appending new messages to the chat
  • Scrolling the chat down to the most recent messages
  • Asking and setting the user name
  • Limiting the text input to prevent gigantic ridiculous messages
  • Basic security
