What are some best practices for optimizing performance when sorting data in PHP?

When sorting data in PHP, it is important to use the most efficient sorting algorithm for the size and type of data being sorted. For large datasets, consider using sorting functions like `usort()` or `uasort()` which allow custom comparison functions. Additionally, avoid unnecessary data manipulation within the sorting loop to improve performance. 

// Example of sorting an array using usort() with a custom comparison function
$data = [3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5];
usort($data, function($a, $b) {
    if ($a == $b) {
        return 0;
    }
    return ($a < $b) ? -1 : 1;
});

print_r($data);
