It would be a lot easier if you were to use IIS, it only takes about 30 seconds to configure php to run.
//////////////////////////////////////////
this may sound stupid but you never know//
//////////////////////////////////////////
make sure you are typing in the file name of your php page like: "http://localhost/yourscript.php3" and not just double clicking on the file to try and open it!
///////////////////////////////////////////
You should have a look at your "file types" allocation under "view"....."folder options" or something like that in my computer or windows explorer, etc. See if there is an extention called .php3 and if there is see what it is being opened with. If there isn't then you may want to create one and have it open with explorer or netscape.
Then in your httpd.conf file in Apache/conf/ make sure you added these:
ScriptAlias /php3/ "c:/path-to-php-dir/php.exe"
AddType application/x-httpd-php3 .php3
AddType application/x-httpd-php3 .phtml
Action application/x-httpd-php3 "php3/php.exe"
You should see other similar lines of code already there so you know where to paste everything.
See if this helps.
