Tip: HTTP Query String Parameters Guard

Have you ever wanted to Guard your HTTP Query String Parameters and prevent the user from manipulating them!?

Example:

$limit = $req->query('limit', 10);

http://localhost:8000/users?limit=1  - $limit = 1
http://localhost:8000/users?limit=5  - $limit = 5
http://localhost:8000/users?limit=11 - $limit = 10

Here is how you can do so:
