Compare two ini files with different formats. Will sort the keys and dump php arrays. Really useful for mysql/apache conf.

compare.php

<?php
/**
* INI configurations compare
* 
* Usage: php compare.php file1.ini file2.ini
* Result: Will export sorted arrays into *.res files to use with normal diff tool
