Ask a question about the sort of PHP

I want to sort the arrays numerically, with the following code:

$a = array('a' => 10, 'z' => 10, 'c' => 10, 'b' => 11, 'd' => 10);asort($a, SORT_NUMERIC);var_dump($a);

The printing results are as follows:

array(5) {  'd' =>  int(10)  'a' =>  int(10)  'c' =>  int(10)  'z' =>  int(10)  'b' =>  int(11)}

Problem:

• I need to sort the values (implemented)
• If the values are the same, the order position of the array keys does not change, how do I do

Example:
The above array

$a = array('a' => 10, 'z' => 10, 'c' => 10, 'b' => 11, 'd' => 10);

After sorting, the order of the keys is

D = ten, a = ten, c = ten, z = ten, B = 11

I want to be able to implement the order for

A = ten, z = ten, c = ten, d = ten, B = 11
