Jay,
Your other option is to run a find on the three types of directives you need to add; Action, AddType, and ScriptAlias. Since examples all three directives will already be in your httpd.conf, all you'd need to do is add the coresponding lines underneath the existing examples. Although I'm sure you've seen them already, I've given the directives which need to be added to httd.conf below.
specifies the path to the folder containing the PHP executable
ScriptAlias /php/ "x:/path/to/php/"
specifies the extensions which you want passed to the PHP engine (these are
the typical entries)
AddType application/x-httpd-php .php
AddType application/x-httpd-php .phtml
AddType application/x-httpd-php-source .phps
specifes the name of the PHP executable
Action application/x-httpd-php "/php/php.exe"
All that being said, I'd still recommend that you download EditPlus or something similar. Syntax highlighting is a Good Thing (tm). Hope this helps!!
Cheers,
Geoff
