PHP and Apache 2.0 as Module
PHP: Servers-Apache 2.0 - Manual
If you would like to use PHP as a module in Apache 2.0, be sure to move php4ts.dll for PHP 4, or php5ts.dll for PHP 5, to winnt/system32 (for Windows NT/2000) or windows/system32 (for Windows XP), overwriting any older file. You need to insert these two lines to your Apache httpd.conf configuration file to set up the PHP-Module for Apache 2.0:
Note: Remember to substitute the c:/php/ for your actual path to PHP in the above examples. Take care to use either php4apache2.dll or php5apache2.dll in your LoadModule directive and notphp4apache.dll or php5apache.dll as the latter ones are designed to run with Apache 1.3.x.
