When PHP imports the request query, it handles request parameters like
``foo[bar]=baz`` in a special way as it creates an array. The ``get()`` method
doesn't support returning arrays, so you need to use the following code::
To access request parameters like ``foo[bar]=baz``, you can use the following code::

// the query string is '?foo[bar]=baz'

// don't use $request->query->get('foo'); use the following instead:
$request->query->all('foo');
$request->query->get('foo');
// returns ['bar' => 'baz']

$request->query->get('foo')['bar'];
// returns "baz"

// if the requested parameter does not exist, an empty array is returned:
$request->query->all('qux');
// returns []
