What are the best practices for sorting arrays with strings in PHP to achieve the desired order?

When sorting arrays with strings in PHP, the desired order can be achieved by using the `usort()` function along with a custom comparison function. This allows you to define the specific order in which the strings should be sorted. By specifying the desired order in the comparison function, you can ensure that the array is sorted according to your requirements. 

// Array of strings to be sorted
$strings = ["banana", "apple", "orange", "grape"];

// Custom comparison function to define desired order
function customSort($a, $b) {
    $order = ["apple", "orange", "banana", "grape"];
    $pos_a = array_search($a, $order);
    $pos_b = array_search($b, $order);
    
    return $pos_a - $pos_b;
}

// Sort the array using the custom comparison function
usort($strings, "customSort");

// Output the sorted array
print_r($strings);
