simplexml error handling php

Question

I am using the following code:

function GetTwitterAvatar($username){
$xml = simplexml_load_file(\"http://twitter.com/users/\".$username.\".xml\");
$imgurl =          


        

Answer 1

if (simplexml_load_file($file) !== false) { // continue } else { echo 'Error!'; }

And Twitter is down, maybe ?
