Hello.
If you want using PHP as Apache's module, you can add it to your VirtualHost.
For example:
a) Copying your PHP module to the Apache's modules folder:
cp /usr/local/src/cwp/php-YOUR-VERSION/libs/libphp5.so /usr/local/apache/modules/
Edit your VirtualHost:
b) Disable suPHP
suPHP_Engine off
c) add it to your VirtualHost:
<FilesMatch \.php$>
LoadModule php5_module modules/libphp5.so
SetHandler application/x-httpd-php
</FilesMatch>
d) and restart Apache:
service httpd restart
