使用Facebook Graph Api获取数据

Question

I am trying to get all the facebook group members ids with facebook php sdk, I am getting an array, and can't get out of the array with only ids.

Here is my array:

Array
(
[data] => Array
    (
        [0] => stdClass Object
            (
                [name] => Name Surname
                [administrator] => 
                [id] => 655330041265756
            )

        [1] => stdClass Object
            (
                [name] => Name Surname2
                [administrator] => 
                [id] => 10206563909924840
            )

        [2] => stdClass Object
            (
                [name] => Name Surname3
                [administrator] => 
                [id] => 1035931373098451
            )

I am trying to export only [id], how is this possible?

Answer 1

Just a simple foreach can be used to iterate through the array and extract the id from each object.

foreach ($array as $key=>$value) {
    echo $value->id;
}

Edit: If you want to assign the ids to an array, use the following code:

foreach ($array as $key=>$value) {
     $idArray[] = $value->id;
}

Where $idArray is your array of ids.
