This section contains notes and hints specific to Apache 2.0 installs of PHP on Unix systems.
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 Server.

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.

Example 4-4. Installation Instructions (Apache 2 Shared Module Version)
Following the steps above you will have a running Apache 2.0 with
support for PHP as SAPI module.

To do so append to your configure line in step 6 above either the option

the consequences and understand what you are doing. For more information
read the Apache documentation about the
Note: If you want to use content negotiation, read the Apache MultiViews FAQ.
Note: To build a multithreaded version of Apache your system must support threads. This also implies to build PHP with experimental Zend Thread Safety (ZTS). Therefore not all extensions might be available. The recommended setup is to build Apache with the standard prefork MPM-Module.
