Reorder Multi Dimensional Array using Custom Keys

Question

I have an array like below

Array
(
    [0] => Array
        (
            [text] => one 
            [mp3] => 1.mp3
        )

    [1] => Array
        (
            [text] => two 
            [mp3] => 2.mp3
        )

    [2] => Array
        (
            [text] => three
            [mp3] => 3.mp3
        )

)

And I have another array with index to sort array(1,0,2) ,So With these I want following

 Array
     (

         [0] => Array(
             [text] => two[mp3] => 2. mp3
         )

         [1] => Array(
             [text] => one[mp3] => 1. mp3
         )

         [2] => Array(
             [text] => three[mp3] => 3. mp3
         )

     )

I googled and Found Few solutions on stackoverflow , But None seems to be successful for me

$order=array(1,0,2);
$orderedarray = array_merge(array_flip($order),$myarr);
$myarr = $orderedarray;

print_r($myarr);

Which outputs following

(
    [0] => 0
    [1] => 1
    [2] => 2
    [3] => Array
        (
            [text] => one 
            [mp3] => 1.mp3
        )

    [4] => Array
        (
            [text] => two 
            [mp3] => 2.mp3
        )

    [5] => Array
        (
            [text] => three
            [mp3] => 3.mp3
        )

)

Is there something wrong with my answer?

You need to use array_multisort.

$order =[1,0,2];
array_multisort($myarr, $order);

Var_dump($myarr);
