If you can't use array_column, you can use array_map:

$names = array(
    array('id' => 123, 'name' => 'A'),
    array('id' => 456, 'name' => 'B'),
    array('id' => 789, 'name' => 'C'),
);

$ids = array_map(function ($name) {
    return $name['id'];
}, $names);

var_dump($ids);

// output
array(3) {
    [0] => int(123)
    [1] => int(456)
    [2] => int(789)
}
