Question

I have the following array being returned

Array
    (
        [0] => Array
            (
                [uid] => 616941445
            )

        [1] => Array
            (
                [uid] => 1354124203
            )

    )

However I want just a single layered array, so i would like something like this.

Array
(     
[0] => 616941445
[1] => 1354124203
)

Answer 1

foreach ($arr as $key => $val) {
  $arr[$key] = $val['uid'];
}
