This task involves rewriting and restructuring the installation section of the PHP Manual. This is a large task so may be broken up into smaller parts.
The section in question:
This section has become outdated. For example, we highlight Apache 2.0.x and only include a few notes about Apache 2.2.x. There are a ton of user notes from confused users that should be addressed. The IIS/PWS section is outdated. The Mac section is outdated. Other parts, outdated.
Start work on this one section at a time.
