Handling exceptions within controller methods

[mazuhl]

Is it possible to throw an exception in a controller method and catch that in the dispatcher/router? Controller methods are called in the Dispatcher using call_user_func_array, which doesn't allow for catching exceptions.

If not, how else would you return early from a method?

class MyController {

    public function anyIndex() {
        $this->checkAccess('edit');
    }

    private function checkAccess($permission) {
        if ($userPermission != $permission) throw new Exception("You don't have permission", 401);
    }
}

You are probably using a closure on a filter. If you declare the filter as

$app->router->filter('auth', [MyController::class, 'checkAccess']);

And in the class:

class MyController
{
    public function checkAccess()
    {
        if ($userPermission != $permission) throw new Exception("You don't have permission", 401);
    }
}

It'll catch it
