PHP正则表达式从字符串中提取控制器和动作

Question

So I am developing a Symfony2 application. If you know what i am talking about you know how are routes structured there so I need to extract the routes and their controllers and actions.

I found how to extract the route object but I can't extract the controller and action, but i have the string which has them.

So I have this string: Acme\\SomeBundle\\Controller\\DefaultController::indexAction

All string have similar structure. All strings end with ControllerName::ActionName. Controller name always ends with "Controller" and action name always end with "Action". So I couldnt figure how to extract theese values from the string. I am new to regex I read about it but I don't have any clue how to do this. Please help me, any help apreciated :)

Example string:

`Emca\AnotherBundle\Controller\SecurityController::loginAction`

Example output:

SecurityController
loginAction

I think you can't do this only with one regex but two may be enough. Thank you!

An example can be found in symfony's ControllerNameParser class:

$controller = 'Acme\YourBundle\Controller\SecurityController::loginAction';

if (0 === preg_match('#^(.*?\\\\Controller\\\\(.+)Controller)::(.+)Action$#', $controller, $match)) {
    throw new \InvalidArgumentException(sprintf('The "%s" controller is not a valid "class::method" string.', $controller));
}

$className      = $match[1];
$controllerName = $match[2];
$actionName     = $match[3];
