You can make use of the array_walk function as:

$arr = array(
        array("name" => "Jack", "id" => 1),
        array("name" => "Rose", "id" => 2),
    );

$result = array(); // initialize result array.
array_walk($arr, "filter"); // iterate over the array calling filter fun for each value.
// $result will now have elements "Jack" and "Rose"

function filter($a) {

    global $result; // to access the global result array.

    $result[] = $a['name']; // for each array passed, save the value for the key 'name' in the result array.
}
