php help

Dear support, I'm a teacher from 1 of the International Schools in the Philippines and I need your help regarding running php. I've read some threads stating that they didn't get any response from you guys, at least I tried. So here's the situation: OS: Windows 98 SE PWS I installed PWS and tested it. It's working just fine. When I click the http://mike-naya, I get the default.asp(as my personal page) displayed in IE. I extracted php-4.3.8-Win32.zip to drive c:\ and renamed the folder to php(c:\php). I installed the php-4.3.8-installer.exe and did the instructions found in c:\php\install.txt. I tried to run c:\>php\php.exe -i and got the postinfo.html data, so that means my PHP installation is working also. However, when I run my index.php(with this content only <?php phpinfo();?> ) using IE-http://localhost/index.php, I got a bad error request. I tried to run postinfo.htm using http://localhost/postinfo.html & it's working... Please don't redirect me to "read your installation manual" because I've done it for a couple of times & I still wasn't able to make my PHP run... Always, Mike
