    $friend_ids_arr[] = $friend['id'];

エラー：

Warning: Invalid argument supplied for foreach() in /blah/data.php on line 14

変数の通過を妨げていることはありますか?

$_SESSION['user']問題なく印刷されるので、問題は次の行にあると思います。

$_SESSION['friends'] = $facebook->api('/me/friends');

私が見たところ、fbconnect.phpではセッションを開始していません。session_start（）;を挿入してみてください。connect（）の後。

data.php が fbconnect.php にどのように結び付いているかはわかりませんが、使用したいかもしれません

$friends = $_SESSION['friends'];

前

$arr = $friends['data'];
