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.

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.
Specify whether PHP scripts may request child process termination on end of request, see also apache_child_terminate().
Send PHP scripts modification date as Last-Modified: header for this request.
