What to use instead of getRequest()->get(...) in controller

Question

Recently I browsed symfony2 api docs and here is what i've found in documentation for Request's get method:

Avoid using this method in controllers:

• slow
• prefer to get from a "named" source

So what is the "named" source that I should use instead of get method?

Answer 1

"named" source would be appropriate parameter bag:

• $request->query for GET parameters
• $request->attributes for request attributes (parsed from PATH_INFO)
• $request->request for POST parameters

get method simply goes through all of them until it finds a parameter by name. Therefore its slow. See the implementation.
