Installing as an Apache module
You need to insert these two lines to your Apache httpd.conf configuration file to set up the PHP module for Apache 2.x:
Code:
# For PHP 4 do something like this:
LoadModule php4_module "c:/php/php4apache2.dll"
# Don't forget to copy the php4apache2.dll file from the sapi directory!
AddType application/x-httpd-php .php
# For PHP 5 do something like this:
LoadModule php5_module "c:/php/php5apache2.dll"
AddType application/x-httpd-php .php
# configure the path to php.ini
PHPIniDir "C:/php"
Note: Remember to substitute your actual path to PHP for the c:/php/ in the above examples. Take care to use either php4apache2.dll or php5apache2.dll in your LoadModule directive and
not php4apache.dll or php5apache.dll as the latter ones are designed to run with Apache
