Can anyone help??

<?php

set_time_limit(0);

$file = "http://www.example/example.xml";

$rss_channel = array();
$currently_writing = "";
$main = "";
$item_counter = 0;

function startElement($parser, $name, $attrs) {
       global $rss_channel, $currently_writing, $main;
       switch($name) {
           case "RSS":
           case "RDF:RDF":
           case "ITEMS":
               $currently_writing = "";
               break;
           case "CHANNEL":
               $main = "CHANNEL";
               break;
           case "IMAGE":
               $main = "IMAGE";
               $rss_channel["IMAGE"] = array();
               break;
           case "ITEM":
               $main = "ITEMS";
               break;
           default:
               $currently_writing = $name;
               break;
       }
}

function endElement($parser, $name) {
       global $rss_channel, $currently_writing, $item_counter;
       $currently_writing = "";
       if ($name == "ITEM") {
           $item_counter++;
       }
}

function characterData($parser, $data) {
    global $rss_channel, $currently_writing, $main, $item_counter;
    if ($currently_writing != "") {
        switch($main) {
            case "CHANNEL":
                if (isset($rss_channel[$currently_writing])) {
                    $rss_channel[$currently_writing] .= $data;
                } else {

                    //print ("rss_channel[$main][$item_counter][$currently_writing] = $data<br>");
                    $rss_channel[$main][$item_counter][$currently_writing] = $data;
                }
                break;
