What best practices can be recommended for sorting arrays in PHP to optimize performance?

When sorting arrays in PHP, it is recommended to use built-in functions like `sort()` or `asort()` for simplicity and performance optimization. These functions are optimized for sorting arrays efficiently and should be preferred over custom sorting algorithms. Additionally, using the correct sorting function based on the specific requirements (e.g., numeric or associative array sorting) can further improve performance.

// Example of sorting a numeric array using sort()
$numbers = [4, 2, 8, 1, 6];
sort($numbers);
print_r($numbers);
