Closure routes are those routes in which we don’t bind controller and it’s method for url function. Instead we process route function by using closure callback function.
$route->get("<route>", function(){ ... });
When we define route closures, it means we are going to call request function in route file itself.
//...
// route with static message
$routes->get("contact-us", function () {
echo "<h1>Welcome to Online Web Tutor</h1>";
});
// route with view file
$routes->get("about-us", function () {
return view("about-us"); // /app/Views/about-us.php
});
// route with parameter
$routes->get("services/(:num)", function ($id) {
echo "ID: ".$id;
});
//...- /contact-us, /about-us etc route is handled by callback function.
Inside all above route, we didn’t map any controller and method. You can use any method type.
