What potential issues can arise when using array_multisort in PHP?

One potential issue that can arise when using array_multisort in PHP is that it modifies the original arrays passed to it as arguments. To avoid this issue, you can create a copy of the arrays before sorting them using array_multisort.

// Create a copy of the arrays before sorting
$copyArray1 = $array1;
$copyArray2 = $array2;

// Sort the arrays using array_multisort
array_multisort($copyArray1, $copyArray2);

// $copyArray1 and $copyArray2 are now sorted while the original $array1 and $array2 remain unchanged
