Getting users profile image in PHP via curl doesn't work

I need the users image as image object within PHP.
The obvious choice would be to do the following:

$url = 'https://graph.facebook.com/'.$fb_id.'/picture?type=large';
$img = imagecreatefromjpeg($url);

This works on my test server, but not on the server this script is supposed to run eventually (allow_url_fopen is turned off there).

So I tried to get the image via curl:

function LoadJpeg($url) {
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0);
  $fileContents = curl_exec($ch);
  curl_close($ch);
  $img = imagecreatefromstring($fileContents);

  return $img;
}

$url = 'https://graph.facebook.com/'.$fb_id.'/picture?type=large';
$img = LoadJpeg($url);

This, however, doesn't work with facebook profile pictures.
Loading, for example, Googles logo from google.com using curl works perfectly.

Can someone tell me why or tell me how to achieve what I am trying to do?

You have to set

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

in this way you find the image without it you get a 302 response code without image because is in another position set in the field "url" of the response header.

  1. The easiest solution: turn on allow_url_fopen
  2. Facebook most likely matches your user agent.

Spoof it like ...

 // spoofing Chrome
 $useragent="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.13 (KHTML, wie z. B. Gecko) Chrome/13.0.782.215 Safari/525.13.";

 $ch = curl_init();

 // set user agent
 curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
 // set the rest of your cURL options here

I do not have to mention this violates their TOS and might lead to legal problems, right? Also, make sure you follow their robots.txt !
