Apache and PHP

I must be missing something while I had no problem getting perl and SSI working getting PHP to work is eluding me for some reason. I have added this to httpd.conf can someone enlighten me on what may be missing # And for PHP 4.x, use: # AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps if I call it like http://127.0.0.1/cgi-bin/one.php with the shebang line #!php.exe I get the following error No input file specified if I call it without the shebang I get the Internal Server Error Error logs indicate the the #! is needed if I call it in the web root as http://127.0.0.1/one.php4 it prints the code to the screen any insight welcome Thanks going to RRTFM :)
