php.ini search path with CLI api

 [2005-07-27 14:52 UTC] hartmut@php.net

Description:
------------
the first place to look for a php.ini is supposed to be 
the directory where the php binary is installed

this is done by taking the dirname out of 
sapi_module.executable_location
and then appending php.ini

on the other hand sapi_module.executable_location
is just a copy of argv[0] for CLI

so if the CLI is just called as 'php' it looks for php.ini
in "php/php.ini"

a realpath() call should be added somewhere to fix this

Reproduce code:
---------------
strace php 2>&1 | grep php.ini

Expected result:
----------------
php.ini looked for in /usr/local/bin/php.ini

Actual result:
--------------
php.ini looked for in php/php.ini
