Subject: The status quo in PHP is that the current directory is initialized
X-Git-Tag: php-4.0.2RC1~28
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1d68a02df36170851b4c3e72faea43129022642e;p=php

The status quo in PHP is that the current directory is initialized
to the directory where the executing script is located.

Since this needs to be implemented for all SAPI modules anyway, this
change moves the functionality to php_execute_script() and gets rid
of the per-module code.
