This section contains notes and hints specific to Apache 2.0.x installs of PHP on Microsoft Windows systems. We also have instructions and notes for Apache 1.3.x users on a separate page.
Note: You should read the manual installation steps first!
We do not recommend using a threaded MPM in production with Apache2. Use the prefork MPM instead, or use Apache1. For information on why, read the related FAQ entry on using Apache2 with a threaded MPM
You are highly encouraged to take a look at the Apache Documentation to get a basic understanding of the Apache 2.0.x Server. Also consider to read the Windows specific notes for Apache 2.0.x before reading on here.
PHP and Apache 2.0.x compatibility notes: The following versions of PHP are known to work with the most recent version of Apache 2.0.x:
These versions of PHP are compatible to Apache 2.0.40 and later.
- 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.
Apache 2.0 SAPI-support started with PHP 4.2.0. PHP 4.2.3 works with Apache 2.0.39, don't use any other version of Apache with PHP 4.2.3. However, the recommended setup is to use PHP 4.3.0 or later with the most recent version of Apache2.
All mentioned versions of PHP will work still with Apache 1.3.x.
Apache 2.0.x is designed to run on Windows NT 4.0, Windows 2000 or Windows XP. At this time, support for Windows 9x is incomplete. Apache 2.0.x is not expected to work on those platforms at this time.
There are two ways to set up PHP to work with Apache 2.0.x on Windows. One is to use the CGI binary the other is to use the Apache module DLL. In either case you need to edit your httpd.conf to configure Apache to work with PHP and then restart the server.
Note: Remember that when adding path values in the Apache configuration files on Windows, all backslashes such as c:\directory\file.ext must be converted to forward slashes, as c:/directory/file.ext.
You need to insert these three lines to your Apache httpd.conf configuration file to set up the CGI binary:
By using the CGI setup, your server is open to several possible attacks. Please read our CGI security section to learn how to defend yourself from those attacks.
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 6-6. PHP and Apache 2.0 as Module
Note: Remember to substitute the c:/php/ for your actual path to PHP in the above examples. Take care to use either php4apache2.dll or php5apache2.dll in your LoadModule directive and not php4apache.dll or php5apache.dll as the latter ones are designed to run with Apache 1.3.x.
Note: If you want to use content negotiation, read related FAQ.
Don't mix up your installation with DLL files from different PHP versions. You have the only choice to use the DLL's and extensions that ship with your downloaded PHP version.
