PHP and Apache

Hi, I'm using Apache 1.3 on my Windows XP Pro box with PHP 5. I'm trying to get Apache to reconize it. I've added "LoadModule php5_module "c:/PHP/php5apache.dll"" and "AddModule mod_php5.c" to the httpd.conf file. I restart Apache, but it throws a santax error that says that the module [mod_php5.c] is not in the loaded modules list and that it cannot be loaded. I have double checked the directory that PHP is in. Is it bad that I cannot find "mod_php5.c" in that directory? I can find php5apache.dll, just not the .c file. Can anyone help me? Thanks! ./ Logan
