Servers-Apache 2.0

PHP and Apache 2.0 compatibility notes

The following versions of PHP are known to work with the most recent version of Apache 2.0:

• PHP 4.3.0 or later available at http://www.php.net/downloads.php.
• the latest stable development version. Get the source code http://snaps.php.net/php4-latest.tar.gz or download binaries for windows http://snaps.php.net/win32/php4-win32-latest.zip.
• a prerelease version downloadable from http://qa.php.net/.
• you have always the option to obtain PHP through anonymous CVS.

PHP and Apache 2 on Linux

Download the most recent version of Apache 2.0 and a fitting PHP version from the above mentioned places. This quick guide covers only the basics to get started with Apache 2.0 and PHP. For more information read the Apache Documentation. The version numbers have been omitted here, to ensure the instructions are not incorrect. You will need to replace the 'NN' here with the correct values from your files.

1.  gzip -d httpd-2_0_NN.tar.gz
2.  tar xvf httpd-2_0_NN.tar
3.  gunzip php-NN.tar.gz
4.  tar -xvf php-NN.tar
5.  cd httpd-2_0_NN
6.  ./configure --enable-so
7.  make
8.  make install

    Now you have Apache 2.0.NN available under /usr/local/apache2,
    configured with loadable module support and the standard MPM prefork.
    To test the installation use your normal procedure for starting
    the Apache server, e.g.:
    /usr/local/apache2/bin/apachectl start
    and stop the server to go on with the configuration for PHP:
    /usr/local/apache2/bin/apachectl stop.

9.  cd ../php4-NN
10. ./configure --with-apxs2=/usr/local/apache2/bin/apxs
11. make
12. make install
13. cp php.ini-dist /usr/local/lib/php.ini

    Edit your php.ini file to set PHP options. If
    you prefer this file in another location, use
    --with-config-file-path=/path in step 10.

14. Edit your httpd.conf file and check that these lines are
    present:
  
   LoadModule php4_module modules/libphp4.so
   AddType application/x-httpd-php .php

  You can choose any extension you wish here. .php is simply the one
  we suggest.
 
  The path on the right hand side of the LoadModule statement must point
  to the path of the PHP module on your system. The above statement is
  correct for the steps shown above.

15. Use your normal procedure for starting the Apache server, e.g.:
   /usr/local/apache2/bin/apachectl start

Following the steps above you will have a running Apache 2.0 with support for PHP as SAPI module. Of course there are many more configuration options available for both, Apache and PHP. For more information use ./configure --help in the corresponding source tree. In case you wish to build a multithreaded version of Apache 2.0 you must overwrite the standard MPM-Module prefork either with worker or perchild. To do so append to your configure line in step 6 above either the option --with-mpm=worker or --with-mpm=perchild. Take care about the consequences and understand what you are doing. For more information read the Apache documentation about the MPM-Modules.

PHP and Apache 2.0 on Windows

Consider to read the Windows specific notes for Apache 2.0.

Download the most recent version of Apache 2.0 and a fitting PHP version from the above mentioned places. Follow the Manual Installation Steps and come back to go on with the integration of PHP and Apache.

There are two ways to set up PHP to work with Apache 2.0 on Windows. One is to use the CGI binary the other is to use the Apache module DLL. In either case you need to stop the Apache server, and edit your httpd.conf to configure Apache to work with PHP.

You need to insert these three lines to your Apache httpd.conf configuration file to set up the CGI binary:

Example 3-7. PHP and Apache 2.0 as CGI ScriptAlias /php/ "c:/php/" AddType application/x-httpd-php .php Action application/x-httpd-php "/php/php.exe"

If you would like to use PHP as a module in Apache 2.0, be sure to move php4ts.dll to winnt/system32 (for Windows NT/2000) or windows/system32 (for Windows XP), overwriting any older file. You need to insert these two lines to your Apache httpd.conf configuration file to set up the PHP-Module for Apache 2.0:

Example 3-8. PHP and Apache 2.0 as Module LoadModule php4_module c:/php/sapi/php4apache2.dll AddType application/x-httpd-php .php
