These functions are only available when running PHP as an Apache module.
Note:
As of PHP 4.3.2, PATH_TRANSLATED is no longer set
implicitly under the Apache 2 SAPI in contrast
to the situation in Apache 1, where it's set to the same value as
the SCRIPT_FILENAME server variable when it's not
populated by Apache. This change was made to comply with the
CGI specification that
PATH_TRANSLATED should only exist if
PATH_INFO is defined.
Apache 2 users may use AcceptPathInfo = On inside
httpd.conf to define PATH_INFO.
The behaviour of the Apache PHP module is affected by settings in php.ini.
Configuration settings from php.ini may be overridden by
php_flag settings
in the server configuration file or local .htaccess files.

Here's a short explanation of
the configuration directives.
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
server basis. By putting engine off
in the appropriate places in the httpd.conf file, PHP can
be enabled or disabled.
