Re: Chat with php

Simple trick (well, not so simple, but kind of a Columbus' Egg): 1) Create an <img> tag in your web page that is hidden 2) Point the img tag to a php script that returns: 1) An image with a pixel width of 1 if there is new data to pick up from the server 2) An image with a pixel width of 0 otherwise 3) Create a javascript that refreshes the image every second (or every two seconds, or however often you feel necessary--the more often, the more responsive and "real time" your chat system will be). 4) Add an OnLoad event to the img tag that points to a Javascript that checks the width of the newly reloaded image. If the width is one, then you reload your chat text content (which you may want to put in an iframe to avoid having to reload the whole page). I don't have a script to show unfortunately, as it would probably be too complicated and long for the list (and I have no time to write it...<sigh>), but hopefully, this will give you the gist of it.
