For convenience, some commonly used regular expression patterns have helper methods that allow you to quickly add pattern constraints to your routes:

example :

$router->get('/user/:id/:name', function () {
    // ...
})->whereNumber('id')->whereAlpha('name');

If the incoming request does not match the route pattern constraints, an exception will be returned.

When running the commands "composer controller" for instance, it fails with the following error code:
Script cd vendor/devamirul/p-router/src/CLI && php createController.php && cd - handling the controller event returned with error code 1
