X-Git-Tag: php-4.3.0dev-ZendEngine2-Preview1~589
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=3aa8a9b62b5cc7389ff08f9da0b15aede95a3114;p=php

This patch implements a new Apache2 directive called PHPINIDir that
allows the specification of the php.ini directory from within the Apache
configuration. If left unset, the default is to defer to the hard-coded
php paths. When set, the supplied path is made relative to Apache's
internal ServerRoot setting.

Example:
PHPINIDir "conf"
# PHP will now look in the ServerRoot/conf directory for the php.ini file
---
