What are the potential pitfalls of using a simple foreach loop to sort arrays in PHP?

Using a simple foreach loop to sort arrays in PHP may not be efficient for large arrays as it requires comparing each element with every other element, resulting in a time complexity of O(n^2). To solve this issue, you can use built-in PHP functions like sort(), asort(), ksort(), etc., which have better time complexity for sorting arrays.

// Example of using the sort() function to sort an array
$array = [3, 1, 2];
sort($array);
print_r($array);
