$message = "Hello world!"; if (Validate::isMessage($message)) { echo "Valid message"; } else { echo "Invalid message"; }
use Laminas\Validator\ValidatorInterface; class MessageValidator implements ValidatorInterface { public function isValid($value) { return Validate::isMessage($value); } }This code creates a custom validator class `MessageValidator` that implements the `ValidatorInterface`. This validator uses the `Validate::isMessage()` function to check the validity of the given value. The `Validate::isMessage()` function is not a built-in PHP function. It is possible that it is part of a custom library or framework.
