I successfully loaded the friends array containing more arrays into a variable. But how do I iterate through it to take only the id's out?
I used:
$friends = $facebook->api('/me/friends/');
It returns a multidimensional array like so:
array(1) { ["name"] => "Username" ["id"] => "User ID #"}
array(2) { ["name"] => "Username" ["id"] => "User ID #"}
...and so on...
Any help would be appreciated! Thanks.
Results of Graph API almost always contain data property which is contain all the response data, to get only the friends ids you can look over it in such way:
// If all you need is users ids, specify it in fields url argument
$friends = $facebook->api('/me/friends/?fields=id');
$data = $friends['response'];
$friendsIds = array();
for ($data as $user){
$friendsIds[] = $user['id'];
}
Try:
$yourIdArr = array();
foreach($yourFriendArray as $key => $val) {
if("id" == $key) {
array_push($yourIdArr, $val);
}
}
$friends (result from $facebook->api('/me/friends/') ) ? Isn't there a ['data'] index on it where all the sub-arrays are stored ?
$val is really an array which contain id key, $key in this case is a numeric index...
