Reading results from PHP Facebook Graph api SDK - php

Question

I am trying to get a list of all the names & id of people actually going to an event I create. Getting the list using the php graph api for facebook was the easy part and seems to work.
Code (php) the get the data:
//GET ATTENDING
$getattending = "/" . $event_id . "/attending?fields=name,id";
$req_events = new FacebookRequest($session, 'GET', $getattending);
$req_response = $req_events->execute();
$data_array = $req_response->getGraphObject()->asArray();
$counter = array_map("count", $data_array);
$count = $counter['data'];
echo "Attending: $count<BR>";
echo "<PRE>";
print_r($data_array);
echo "</PRE>";
The result:
Array (
[data] => Array
(
[0] => stdClass Object
(
[name] => Thierry Martens
[id] => 788923242
)
[1] => stdClass Object
(
[name] => Lisa Mario Laurier
[id] => 708876902536391
)
[2] => stdClass Object
(
[name] => Ramy Mahfoudhi
[id] => 735036479911364
)
[3] => stdClass Object
(
[name] => Jeremy Verriest Duroisin
[id] => 783108468420824
)
[4] => stdClass Object
(
[name] => Jonas En Svetlana Laurier
[id] => 773139856081632
)
[5] => stdClass Object
(
[name] => Maxime Demerliere
[id] => 849400761761008
)
[6] => stdClass Object
(
[name] => Jeremy Beauchamp
[id] => 10204174155667109
)
[7] => stdClass Object
(
[name] => Sari Jens Delcourte Delusinne
[id] => 10204086515874904
)
[8] => stdClass Object
(
[name] => Pieter Marysse
[id] => 10204911283045115
)
[9] => stdClass Object
(
[name] => Patrick Vanden Bosschelle
[id] => 10202907209181148
)
)
BUT i am having problems to actually gather the data itsels; i simply need the name and the id in simple array or list so i can use it in the rest of the script. Any ideas Anyone?
My second question is the php graph api seems to have a "/eventnr/attending" thing for graph 2.1; showing nr attendants to your event in question; but when i actually call it i get an error stating i need to use graph 2.1 while i uploaded the latest php sdk and can't seem to find a way to change that version. This question is not as important as the one above; but if it works i would need less code :)
Hope you guys can help me :)

Answer 1

!!!! GOT IT !!!!
Did look some further on here and the solutions seems to be pretty easy:
for ($x = 0; $x <= $count; $x++)
{
$names[$x] = $data_array['data'][$x]->name;
$ids[$x] = $data_array['data'][$x]->id;
}
Displays:
$names array:
Array ( [0] => Thierry Martens [1] => Lisa Mario Laurier [2] => Ramy
Mahfoudhi [3] => Jeremy Verriest Duroisin [4] => Jonas En Svetlana
Laurier [5] => Maxime Demerliere [6] => Jeremy Beauchamp [7] => Sari
Jens Delcourte Delusinne [8] => Pieter Marysse [9] => Patrick Vanden
Bosschelle [10] => )
$ids array:
Array ( [0] => 788923242 [1] => 708876902536391 [2] => 735036479911364
[3] => 783108468420824 [4] => 773139856081632 [5] => 849400761761008
[6] => 10204174155667109 [7] => 10204086515874904 [8] =>
10204911283045115 [9] => 10202907209181148 [10] => )

Answer 2

It's like:
$dataArray = $data_array['data'];
$firstPerson = new $dataArray[0];
echo $firstPerson->name;
echo $firstPerson->id;
Maybe you need this, though:
foreach($data_array['data'] as $a){
$o = new $a; $names[] = $o->name; $ids[] = $o->id;
}
// $names is Array of names
// $ids in Array of ids

Answer 3

I added your code but result is the following (empty arrays)
added code:
foreach($data_array['data'] as $a)
{
$o = new $a; $names[] = $o->name; $ids[] = $o->id;
}
echo "FIRST ELEMENT - \$data_array['data'][0]: <BR>";
print_r($data_array['data'][0]); echo "<BR><BR>";
echo "\$names array: <BR>";
print_r($names); echo "<BR><BR>";
echo "\$ids array: <BR>";
print_r($ids); echo "<BR><BR>";
Result of the echo & print_r:
FIRST ELEMENT - $data_array['data'][0]:
stdClass Object ( [name] => Thierry Martens [id] => 788923242 )
$names array:
Array ( [0] => [1] => [2] => [3] => [4] => [5] => [6] => [7] => [8] => [9] => )
$ids array:
Array ( [0] => [1] => [2] => [3] => [4] => [5] => [6] => [7] => [8] => [9] => )
