Question

So here is my array, what I want to do is unset the [detail][$x] keys leaving just the lowest total. Can anyone assist? Thank you in advance..

There is alot of Products to loop though, what I mean is that its not just one item in the array.

[1] => Array
        (
            [name] => Product Name 1
            [detail] => Array
                (
                    [1] => Array
                        (
                            [total] => 10.14
                        )

                    [2] => Array
                        (
                            [total] => 12.18
                        )

                    [3] => Array
                        (
                            [total] => 9.90
                        )

You can find out the lowest total and overwrite the whole detail. Something like that:

$lowestValue = false;
foreach ($array[1]['detail'] as $detail) {
    if ($lowestValue === false || $lowestValue > $detail['total']) {
        $lowestValue = $detail['total'];
    }
}

$array[1]['detail'] = array(0 => array('total' => $lowestValue));
