Filter out [ 0 => null ] parameters by default

When send request using types[]=, the received input is:

[
    0 => null,
]

Which will go into the filter methods.

This is not wanted.

Technically that is the desired behavior and the check should lie in the filter method for that input or you can remove it in the setup method of the filter. #58 gives some insight as to why I wouldn't want to check or exclude values based on the content of an array.

If you want to not forward that to the filter method that handles that input you can add an input filter to your setup method:

public function setup()
{
    $this->input = array_filter($this->input, function($val) {
        return !(is_array($val) && count($val) === 1 && $val[0] === null);
    });
}
