how to setup PHP in httpd.conf?

[Anon]

I have installed php4 as apache module, it works well.But when I want to setup PHP in httpd.conf (such as "php_engine on"),the system reported error:
Invalid command 'php_engine', perhaps mis-spelled or defined by a module not included in the server configuration

You are mistaken the Php_engine is a part of the php.ini file which needs to be a part of the /usr/lib and more over in httpd.conf you just need to add extension types like below

AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps

And restart your web server again, thats all.
