$request->getParameter with array - Symfony

Question

If I have:

$_POST['test']

then can I use:

$request->getParameter('test');

But how can I use this if I have $_POST['test']['two']?

Answer 1

Now only one way do to it:

$arr = $request->getParameter('test');
$two = $arr['two'];

Edited:

In PHP 5.4 you can do it $request->getParameter('test')['two'];

Answer 2

$request->getParameter('test')['two'];

Answer 3

As of Symfony 2, there's even a prettier solution to get array values with the Symfony Request:

$request->get("test[two]", null, true)

The third parameter of get(), $deep, is false by default and decides whether you can access array keys.

See the documentation of the ParameterBag:

boolean $deep: If true, a path like foo[bar] will find deeper items
