Defining PHP varibles from URL

I don't mean to be a pain but could someone send me a working example? I am what you would probably call a 'newbie' For those who don't know here is my previous message can't seem to define a varible from the url entered into a browser. I wish to use the following code or something like it. <script language="php"> $file = ""; //the above is defined from the url include "$file"; </script> It could be what I was typing in the url bar. file.php?file=foobar.inc Thanks, JJ Harrison webmaster@tececo.com www.tececo.com
