Custom sorting an array in PHP

Question

I have a simple array that I would like to sort in the following way: Critical, Major, Moderate, Minor

Array
    (
        [Major] => 9
        [Critical] => 5
        [Moderate] => 6
        [Minor] => 5
    )

I am not sure how to go about custom sorting based on the key in PHP

Answer 1

Something like this should work for you.

$arr = ['Major' => 9, 'Critical' => 5, 'Moderate' => 6, 'Minor' => 3];
function cmp($a, $b) {
    $order = ['Critical' => 0, 'Major' => 1, 'Moderate' => 2, 'Minor' => 3];
    return $order[$a] - $order[$b];
}

uksort($arr, "cmp");
