Stuck with regular expression

Question

Coming from another answer, I am stuck with a regexp (what are the odds...?).

$matches    = array();
// $controller = $this->getRequest()->attributes->get('_controller');
$controller = "Acme\MyBundle\Controller\MyController::myAction";
preg_match('/(.*)\\\Bundle\\\(.*)\\\Controller\\\(.*)Controller::(.*)Action/', $controller, $matches);

print_r($matches);

Returns ( see example )

Array
(
)

Expected result

Array
(
    [0] => Acme\MyBundle\Controller\MyController::myAction
    [1] => Acme
    [2] => My
    [3] => My
    [4] => my
)

Anyone can help? This regexp seems to be legit, maybe it's just a problem with the backslashes? I tried around but didn't get it.

Answer 1

Please try below expression. Is it expected? Or tell me your exact requirements.

<?php

$matches    = array();
// $controller = $this->getRequest()->attributes->get('_controller');
$controller = "Acme\MyBundle\Controller\MyController::myAction";
preg_match('/(.*)\\\(.*)Bundle\\\Controller\\\(.*)Controller::(.*)Action/', $controller, $matches);

print_r($matches);
