What are some potential pitfalls to avoid when sorting arrays in PHP using array_multisort?

One potential pitfall to avoid when sorting arrays in PHP using array_multisort is ensuring that the arrays being sorted are of the same length. If the arrays have different lengths, array_multisort may not behave as expected and can lead to incorrect sorting results. To solve this issue, you should first check the lengths of the arrays and make sure they are equal before sorting. 

// Example code snippet to avoid sorting arrays of different lengths using array_multisort
$array1 = [3, 1, 2];
$array2 = ['c', 'a', 'b'];

if (count($array1) === count($array2)) {
    array_multisort($array1, $array2);
    // continue with further processing of sorted arrays
} else {
    echo "Arrays must be of the same length for sorting.";
}
