Viewing Multiple RSS

[ashrafzia]

I want to acess RSS from different sites.
I have the following code for viewing RSS from different Sites.
Error is: Only Last Link i-e cnn_law.rss is retriewing others are not!
if i don't take $file as an array and only take one URL then its working fine but in case of array its not working and giving the above error.

[code]
<?php

set_time_limit(0);

$file[0] = "http://rss.cnn.com/rss/cnn_topstories.rss";
$file[1] = "http://rss.cnn.com/rss/cnn_health.rss";

$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";
