What are the potential pitfalls of using array_multisort() in PHP for sorting arrays?

One potential pitfall of using array_multisort() in PHP for sorting arrays is that it modifies the original arrays passed to it. To avoid this issue, you can make a copy of the arrays before sorting them. This way, the original arrays remain unchanged.

// Create a copy of the arrays before sorting
$array1_copy = $array1;
$array2_copy = $array2;

// Sort the arrays using array_multisort
array_multisort($array1, $array2);

// Now $array1 and $array2 are sorted, but $array1_copy and $array2_copy remain unchanged
