[Easymod-cvs] easymod2/dev xml_to_array.php,NONE,1.1

[Brendan K. <bk...@us...>]

Update of /cvsroot/easymod/easymod2/dev
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv7887/dev

Added Files:
	xml_to_array.php 
Log Message:
Some XML to Array parsing code. One method is using a function, another, better method (IMO), is a class based approach using php xml functions.

--- NEW FILE: xml_to_array.php ---
<?php
//
// XML to Array

// parse to array
