How do I route a URL using a query string in Symfony2?

Question

I am re-writing an old project using Symfony2 so I can try out the framework. I have urls that will be of the form:

/profile/{id}

in the snazzy way that Symfony2 does it. However, the same page was originally found by doing:

/profile.php?id=12345

So, in case someone has an old URL, I'd like to redirect these links. The problem is, I don't know how to catch routes of this nature. I tried

/profile.php?id={id}

but that didn't seem to work. How can I set up this route?

Follow-up: I do not want to do "catch-all" (because it is non-intuitive to me so I fear future bugs), and I would prefer not to do it via htaccess for the same reason. I think the best option is to match "/profile.php" then in the controller, check that "id" exists in query-string and redirect accordingly. If it does not, I will redirect to 404.

I see two options here:

You map your old schema (/profile.php?id=54321) onto the new (/profile/54321) using mod_rewrite (in case you use Apache).
You write a mapper within Symfony. That means at the end of your list of routes you specify a pattern that will just catch everything not yet catched:

whatever:
  pattern: /{whatever}
  defaults: { _controller: CoreBundle:Default:whatever }
  requirements:
    whatever: .+

For (2) you will have to check what the Request-object offers you for the queries (like getQueryString()), b/c I am not sure if it is possible to have something like ?xyz being matched in a route.

Would the correct mod_rewrite be: RewriteRule ^profile.php?id=(\d+)$ /profile/$1 [R=301] ?

I just want to verify this is the best strategy, since I'm not an expert in Apache htaccess shenanigans

Me neither. You can test rewrites here: martinmelin.se/rewrite-rule-tester. Though I would prefer to handle that with SF. Because routes are nowadays part of the model/logic.

@raffael1984 post params have nothing to do with routes. He should check the params in his controller, e.g $request->query->getInt('id'). This always returns an integer.

neither me nor martin is talking about POST-parameters
