I usually just lurk on this list, but this is a pet peeve of mine.
Basically php is a programming
language only for websites, you cant use it for desktop programming like perl.
With PHP you can make everything you have ever seen on a website :P forums, sites,tutorials systems, ftp manager, etc
If you want more info about php you can visit my site www.php4all.org
And about putting that in a site, browsers, such as internet explroer, firefox, opera, etc, only "understand" java, flash, and other few languages for game programming
And python is not in that list :P Pygame cannot be added into a website like a flash game :/ At least i have never seen one...
