What are potential pitfalls when using array sorting functions in PHP?

One potential pitfall when using array sorting functions in PHP is that the sorting may not work as expected if the array contains mixed data types. To solve this issue, you can use the `SORT_REGULAR` flag when sorting the array, which will compare elements as they are without changing their types. 

$array = [10, '20', 5, '30'];
sort($array, SORT_REGULAR);
print_r($array);
