PHP per-directory INI settings

Most of the configuration variables can be set on a per-directory basis. This can be used when you have a single web server that is serving multiple applications, and:

• You want to use a different application name for each of those applications.
• You want to tweak certain settings on an application by application basis.

The mechanism to set per-directory values depends on the environment. This document describes the three most common environments (Apache, php-fpm, and nginx).
