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

When using array_multisort() in PHP for sorting arrays, one potential pitfall is that the function modifies the original arrays directly, which may not be desired if you want to preserve the original data. To solve this issue, you can make a copy of the array before sorting it using array_multisort().

// Create a copy of the original array
$originalArray = $arrayToSort;

// Sort the array using array_multisort()
array_multisort($arrayToSort);

// Now $arrayToSort is sorted, but $originalArray remains unchanged
