This example demonstrates how to validate strings in PHP using the Composer package respect-validation.


        <?php
        require 'vendor/autoload.php'; // Autoload Composer packages

        use Respect\Validation\Validator as v;

        // Create a string validator
        $stringValidator = v::stringType()->length(1, 50); 

        // Example string to validate
        $stringToValidate = "Hello, World!";

        // Validate the string
        if ($stringValidator->validate($stringToValidate)) {
            echo "Valid string.";
        } else {
            echo "Invalid string.";
        }
        ?>
