I. Apache-specific Functions

Introduction

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

Not: PATH_TRANSLATED server variable is no longer set implicitly under Apache 2 SAPI in contrast to the situation in Apache 1, where it is set to the same value as the SCRIPT_FILENAME server variable when it is not populated by Apache. This change was made to comply with the CGI specification. Please refer to bug #23610 for further information.

Installation

For PHP installation on Apache 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.

�rnek 1. Turning off PHP parsing for a directory using .htaccess

php_flag engine off

Tablo 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 regardless 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.

here is a dynamic version of henk_nicolai at REMOVE-THIS at hotmail dot com's code



    $req = $_SERVER['REQUEST_URI'];

    // Remove rubbish.

    $newReq = ereg_replace ( $_SERVER['SCRIPT_NAME'] . '[^?]*', $_SERVER['SCRIPT_NAME'], $req);

    if (strlen($newReq) < strlen($req)) 

    {

        header ('Location: '.$newReq);

        header ('HTTP/1.0 301 Moved Permanently');

        die;  // Don't send any more output.

    }

    unset($req); 

    unset($newReq);



this can be placed at the top of any file that is to be access by the URI.

to henk_nicolai



the behaviour you describe is not a "glitch" of apache :-). an url like

"http://my_server.nl/index.php/foo".  should return the resource http://my_server.nl/index.php and pass "/foo" as PATH_INFO in the environment. 



which is extremely usefull if you use it wisely. 



for more info on PATH_INFO and PATH_TRANSLATED, see http://nl2.php.net/reserved.variables . PATH_INFO is not related to the php pathinfo() function

Important info for Apache2 users that have several virtual hosts.



It seems php_flag directive has a different behaviour under Apache 2 (from what it is under 1.3) when used inside <VirtualHost> block.



If you override global php.ini settings with php_flag for one of your virtual host - then your other non-customized virtual hosts may use this overrided settings as well. php_flag records are messed up among different virtual hosts under single Apache 2 server. It may result from Apache 2 multi-thread nature.



Here is an example:



Suppose you have two Virtual hosts: V1 and V2.

For V1 in Apache configuration you use

php_flag magic_quotes_gpc 1

V2 is supposed to use global php.ini settings, so you didn't put any php_flag records into Apache conf for V2 (this worked under Apache 1.3).

And your default php.ini settings are: 

php_flag magic_quotes_gpc 0



When you run your server you'll notice that magic quotes is (sometimes) set to On at V2!

The value turns On at V2 when there have been a previous request to V1.



To solve the problem either move php_flag into .htaccess located inside customized virtual host directory OR put php_flag with default settings into all your <VirtualHost> blocks that are not customized. So for V2 put:

php_flag magic_quotes_gpc 0



It is critical to be very carefull with php_flag engine 0.



My configuration is:

PHP 4.3.4, Apache 2.0.50, Linux RedHat 9

My Apache server has a problem when someone enters a URI like: "http://my_server.nl/index.php/". (Note the extra slash.) The server executes the index.php script anyway, which causes the browser directory and the current directory used in the script to be different. And therefore my relative links don't work, and my stylesheet is not loaded. A quick test ("http://www.php.net/manual/en/index.php/") reveals that also this site has this glitch. 



When a client requests a directory without the last slash ("http://www.php.net/manual") the server sends a HTTP 301 (Moved Permanently) response with a redirect to the correct URI ("http://www.php.net/manual/"), and my idea was to do the same when the user adds a slash too much:



<?php

   $req = $_SERVER['REQUEST_URI'];

   // Remove rubbish.

   $newReq = ereg_replace ('index.php[^?]*', 'index.php', $req);

   if (strlen($newReq) < strlen($req)) {

     header ('Location: '.$newReq);

     header ('HTTP/1.0 301 Moved Permanently');

     die;  // Don't send any more output.

   }

   unset($req); unset($newReq);



   ... (rest of the script) ...

?>



Replace every occurence of 'index.php' with your filename and you're done. Hope it helps. :-)



(Note: I'm not using fragments in my URI's (like 'index.php#bottom'), and this code may not do what you want if you are using them.)

If you are trying to find a Handler to use with apache's mod_mime functions (e.g. SetHandler).  Use the MIME type associated with php.



e.g. SetHandler application/x-httpd-php
