Are there potential pitfalls to be aware of when sorting arrays in PHP?

When sorting arrays in PHP, one potential pitfall to be aware of is that the sort() function in PHP sorts arrays in place, meaning it modifies the original array rather than returning a new sorted array. If you need to preserve the original array, you can make a copy of it before sorting.

// Create a copy of the original array before sorting
$originalArray = [3, 1, 2];
$sortedArray = $originalArray;
sort($sortedArray);

// $sortedArray will now be sorted, while $originalArray remains unchanged
