How to swap positions of two elements of an associative array?

Question

PHP

array

$arr = [
    'a' => 10,
    'b' => 20,
    'c' => 50, // поменять местами 
    'd' => 40, // с этим
    'e' => 10,
];

you need to change the element with the keys 'c'and 'd'places to get:

[
    'a' => 10,
    'b' => 20,
    'd' => 40,
    'c' => 50,
    'e' => 10,
];

How can you control the position of elements in an array in PHP, other than sorting and shift/unshift/push/pop ?

Answer 1

It seems that it is impossible to simply remember in places, without rewriting the entire array.
So either a numbered array, or cut-and-glue.
