php - file_get_contents give random older images from Facebook image profile -


i have simple php script, image facebook , download user profile image server.

  $url = 'https://graph.facebook.com/'.$iduser.'/picture?width=200&height=200&redirect=false';   $data = json_decode(file_get_contents($url), true);   $url = $data["data"]["url"];   $path = $iduser.'.jpg';   file_put_contents ($path, file_get_contents($url));

in cms site try open user profile page, time execute script, because want see actual user profile image. when user change user profile image script wrong. file_get_contents download old image, when refresh page or new image randomly. mean? error?
