在多维数组中查找子数组

Question

I have a multidimensional array and would like to find an array by specific payment_status: My array below and I would like to return an array by payment_status.

[orders] => Array
        (
            [0] => Array
                (
                    [total_price] => 995.94
                    [avg] => 995.940000
                    [count] => 1
                    [payment_status] => 1
                )

            [1] => Array
                (
                    [total_price] => 779.64
                    [avg] => 779.640000
                    [count] => 1
                    [payment_status] => 2
                )

            [2] => Array
                (
                    [total_price] => 1763.49
                    [avg] => 1763.490000
                    [count] => 1
                    [payment_status] => 3
                )

function get_sub_array((int)$payment_status) {

}

How can I do this? Thanks!

$arr = array('orders' => array
        (
            0 => Array
                (
                    'total_price' => 995.94,
                    'avg' => 995.940000,
                    'count' => 1,
                    'payment_status' => 1
                ),

            1 => Array
                (
                    'total_price' => 779.64,
                    'avg' => 779.640000,
                    'count' => 1,
                    'payment_status' => 2
                ),

            2 => Array
                (
                    'total_price' => 1763.49,
                    'avg' => 1763.490000,
                    'count' => 1,
                    'payment_status' => 3
                )
        ));

function get_sub_array($payment_status,$arr) {
  $arrRet = array();
  foreach($arr as $key=>$val){
    if($val['payment_status'] == $payment_status)
      array_push($arrRet,$val);
  }
 return $arrRet;
}

$arrRes = get_sub_array(1,$arr['orders']);
print_r($arrRes);
