PHP - 排序多维分组数组

I'm trying to sort following array:

$myArray = array(
    "ID"    =>  array(
                    0,
                    5,
                    8,
                    12,
                    15
                ),
    "date"  =>  array(
                    1484391600,
                    1483910300,
                    1484920000,
                    1482393630,
                    1484391600
                ),
    "name"  =>  array(
                    "Pete",
                    "Max",
                    "Tom",
                    "June",
                    "Arend"
                ),
);

I want to be able to choose which subarray is sorted and in which way (numeric / string) and order (DESC / ASC). All the other subarrays should be sorted accordingly.

Here is some code that worked at first, but when the subarray to sort contained an empty string, it failed: All subarrays where sorted differently.

$sortCatArray = $myArray['name'];

foreach($myArray as $category => $value){
    $keepOrigin = $sortCatArray;
    array_multisort($keepOrigin, SORT_DESC, SORT_STRING, $myArray[$category]);
}

var_dump($myArray);

Can someone point out what I'm doing wrong.

Also I don't want to rearrange the arrays to match the other sorting solutions as I need the values in the given format.
