php - Symfony - how to generate url with parameters in controller -

i want generate url ../profile/firstname.lastname

but don't understand how can because want in php id user.

this controller:

       $controllers             ->match('profile/{firstname.lastname}/', array($this, 'profile'))             ->assert('userid', '\d+')             ->method('get|post')             ->before(array($this, 'checklogin'))             ->bind('home.profile'); 

you have build route this

<route id="profile" path="/profile/{first_name}.{last_name}">         <default key="_controller">...</default>     </route> 

and in controller create this

$this->generateurl('profile', [ 'first_name' => 'skowron', 'last_name' => 'line' ]);

but if have 2 profiles same data give bad results. can create slug or add id parameter route
