How do I get the total number of friends using the Facebook API and PHP?

Question

How can I get the total number of friends using the Facebook PHP API?

This is my code so far:

<?php require_once 'facebook.php'; 
  $appapikey = 'x'; 
  $appsecret = 'x'; 
  $facebook = new Facebook($appapikey, $appsecret);
  $user_id = $facebook->getuser(); $friends = ???;

Try this

$uid = $facebook->getUser();  
$fbme= $facebook->api('/me');  
echo "Welcome ".$fbme['name'];  
$frnz= $facebook->api('/me/friends');  
echo "< br />Total Number of friends you have:".sizeof($frnz['data'])."< br/>";
