Question

Hello i have an array in php

Array
(
    [0] => red
    [1] => blue
    [2] => green
    [3] => yellow
    [4] => purple
    [5] => white
)

and i want to sort it using that array

Array
(
    [0] => 
    [1] => 0
    [2] => -1
    [3] => -5
    [4] => -5
    [5] => 9
)

so i want the element with the greatest value on the second array to come first on the first array not its value from the second array but the element it self from the first array to move in the first position on the first array! The second bigger to the second place etc.. elements with the same value don’t care me how they will be arranged!

the output i want to get is

Array
    (
        [0] => white
        [1] => blue
        [2] => green
        [3] => yellow
        [4] => purple
        [5] => red
    )

You can use array_multisort() :

$ar1 = array(/* your SO links */);
$ar2 = array(/* your numbers */);
array_multisort($ar2, SORT_DESC, $ar1);
