For those of you that cannot upgrade to PHP5.5 right now and need this function, here is an implementation of array_column.

function array_column($array, $column){
    $a2 = array();
    array_map(function ($a1) use ($column, &$a2){
        array_push($a2, $a1[$column]);
    }, $array);
    return $a2;
}
