Convert XML data to a PHP Array

why don't you use any class out of the internet?

<?php
class xml2array {

    function xml2array($xml) {
        if (is_string($xml)) {
            $this->dom = new DOMDocument;

            $occurance[$child->nodeName]++;
        }

        if($node->nodeType == XML_TEXT_NODE) {

                                     ENT_COMPAT,'ISO-8859-15');
