Turns PHP parsing on or off.
This directive is really only useful in the Apache module
version of PHP. It is used by sites that would like to turn
PHP parsing on and off on a per-directory or per-virtual

in the appropriate places in the <var class="filename">httpd.conf</var> file, PHP can
be enabled or disabled.
