PHP Random Shuffle Array Maintaining Key => Value

Question

I\'ve been looking on google for the answer but can\'t seem to find something fool-proof and cant really afford to mess this up (going live into a production site).

Answer 1

Answer using shuffle always return the same order. Here is one using random_int() where the order is different each time it is used:

function shuffle_assoc($array)
{
    while (count($array)) {
        $keys = array_keys($array);
        $index = $keys[random_int(0, count($keys)-1)];
        $array_rand[$index] = $array[$index];
        unset($array[$index]);
    }

    return $array_rand;
}
