PHP, Strong Typing, Iteration, Strings

This example demonstrates how to iterate over a string in PHP using strong typing. The output shows each character in a new line.


        <?php
        // Example string
        $string = "Hello World!";
        
        // Strongly typed array from the string
        $characters = str_split($string);
        
        // Iterating over the string with strong typing
        foreach ($characters as string $char) {
            echo $char . "<br>";
        }
        ?>
