Are there any built-in PHP functions that can streamline the process of sorting arrays based on specific criteria?

When sorting arrays in PHP based on specific criteria, you can use the `usort()` function. This function allows you to define a custom comparison function that determines the order of elements in the array. By using `usort()`, you can streamline the sorting process and easily sort arrays based on your desired criteria. 

// Example of sorting an array of numbers in descending order
$numbers = [5, 2, 8, 3, 1];

usort($numbers, function($a, $b) {
    if ($a == $b) {
        return 0;
    }
    return ($a > $b) ? -1 : 1;
});

print_r($numbers);
