Lost in array!

I am retrieving a twitter feed in json, I am converting it to a php array, but I can't seem to succesfully pull vals from it.

<?php
$ch = curl_init();

curl_setopt ($ch, CURLOPT_URL, "http://twitter.com/statuses/public_timeline.json");
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 0);
$twitter = curl_exec($ch);
curl_close($ch);
$twitterArray = json_decode($twitter);
array_walk_recursive($twitterArray, 'Assign');
function Assign(){
	$image=$twitterArray["user"]["profile_image_url"];
	$name=$twitterArray["user"]["screen_name"];
	$description=$twitterArray["user"]["description"];
	$created=$twitterArray["user"]["created_at"];
	$followers=$twitterArray["user"]["followers_count"];
	$friends=$twitterArray["user"]["friends_count"];
	print_r("
		$image\n
		$name\n
		$description\n
		$created\n
		$followers\n
		$friends\n
	");
}
?>

here is a sample of the array:
