php's foreach weird behavior carried out to the Laravel router

[nagi1]

As you might know php's foreach variable after as will be set and can be accessed later down the code i.e.

      $items = [1, 2, 3];

      foreach ($items as $item) {
            // do something with the $item
        }

      var_dump($item)  //  3 => will return the last item in the array 

I found this in RouteCollection class

    protected function addToCollections($route)
    {
        $domainAndUri = $route->getDomain().$route->uri();

        foreach ($route->methods() as $method) {
            $this->routes[$method][$domainAndUri] = $route;
        }

        // $this->allRoutes will only have the last method present in $route->methods()
        $this->allRoutes[$method.$domainAndUri] = $route;

    }

For example if $route->methods() returns ['GET', 'HEAD']. Only HEAD will be added to allRoutes.

I don't know but I find this unexpected and weird, is this intended behavior?
