The nesting of ifs can be reduced here:

        if ($this->strict && is_int($value)) {
            return true;
        }

        if (!$this->strict && filter_var($value, FILTER_VALIDATE_INT) !== false) {
            return true;
        }

        return $this->error(self::NOT_AN_INTEGER);

That's easier to read if you ask me, what do you think?

Hey @rcatlin, thank you for your addition! I have 1 codewise comment, but other than that it's good to go 👍

@RickvdStaaij Thanks for the feedback! I've separated the two conditions and made them more readable.

Perfect, thanks a lot! 👍 Also backwards compatible \o/
