too long

Question

I have a facebook array and I am trying to echo out the names and ID.

All I have is this array: $friends_list.

When I use this code:

print_r($friends_list);

Then the following comes out below: But how do I loop thru these? Or what if I just wanted to find out how many names there are or just call on one var by id. In short how do I echo out $friends_list which is a multiD array?

Array ( [data] => Array ( [0] => Array ( [name] => Wendy Cukierski [id] => 524320383 ) [1] => Array ( [name] => Leticia Mercado Correa [id] => 537763225 ) [2] => Array ( [name] => Olivia Urbina [id] => 538711855 ) [3] => Array ( [name] => Ruth Albrecht [id] => 541610111 ) [4] => Array ( [name] => Josh Brahm [id] => 577546485 ) [5] => Array ( [name] => Kim Yu [id] => 583515871 ) [6] => Array ( [name] => SisterTracey Dugas [id] => 643567171 ) [97] => Array ( [name] => Mary Martinez [id] => 100004696266210 ) ) [paging] => Array ( [next] => https://graph.facebook.com/1566027944/friends?limit=5000&offset=5000&__after_id=100004696266210 ) )

$friends_list = file_get_contents('https://graph.facebook.com/me/friends?access_token=' . $atoken );
    $friends_list_array  = json_decode($friends_list,true);
    $arr= $friends_list_array['data'];
    $friend_ids_arr = array();
    foreach($arr as $friend) {
        $friend_ids_arr[] = $friend['id'];

    $friend_ids = implode("," , $friend_ids_arr);
    echo $friend_ids; // output: id1,id2,id3...etc
