[5.6] Validator should return validated data

[adam1010]

Currently in your controller if you're using:
$data = $request->validate([...]);

If you need to switch to using advanced rules, there is no direct method available for accessing the validated data:

$validator = Validator::make($request->all(), [...]);
$validator->sometimes('phone', 'required', function(){ ... });
$data = $validator->validate();  // This PR adds this return value
