In PHP, how do I sort strings with strong typing?

In PHP, to sort an array of strings with strong typing, you can use the usort function. This allows you to define a custom comparison function where you can compare values strictly.


        <?php
        $strings = ["apple", "Banana", "cherry", "date"];

        usort($strings, function($a, $b) {
            return strcmp(strtolower($a), strtolower($b));
        });

        print_r($strings);
        ?>
