Hello Reader! If you having an multidiamensnal array and you want to get the max value from a single element key then you see the example below:-

[0] => stdClass Object
    (
        [id] => TRF1254
        [cust] => CUST9897
        [amount] => 8974
        [balance] => Array
            (
                [0] => 8987
            )

    )
[1] => stdClass Object
    (
         [id] => TRF1254
        [cust] => CUST9896
        [amount] => 589
        [balance] => Array
            (
                [0] => 8974
            )

    )
[2] => stdClass Object
    (
        [id] => TRF1259
        [cust] => CUST9659
        [amount] => 1258
        [balance] => Array
            (
                [0] =>365
            )

    )

code for sorting:-

  $numbers = array();
    foreach($array as $obj)
    {
        $numbers[] = $obj->amount;
    }
    $max = max($numbers);
