I. Apache-specific Functions
Installation
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.
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 |
| xbithack | Off | PHP_INI_ALL | parse files with executable bit set as PHP regardles of their file ending |
Here's 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.
