I. Apache-specific Functions


These functions are only available when running PHP as an Apache 1.x module.


For PHP installation on Apache 1.x see the Apache section in the installation chapter.

Runtime Configuration

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.

Example 1. Turning off PHP parsing for a directory using .htaccess

php_flag engine off

Table 1. Apache configuration options

Name Default Changeable Function
engine On PHP_INI_ALL turns PHP parsing on or off
child_terminate Off PHP_INI_ALL specify whether PHP scripts may request child process termination on end of request, see also apache_child_terminate()
last_modified Off PHP_INI_ALL send PHP scripts modification date as Last-Modified: header for this request
xbit_hack Off PHP_INI_ALL parse files with executable bit set as PHP regardles of their file ending

Here is a short explanation of the configuration directives.

engine boolean

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.
