function my_custom_function() { // do something } add_action( 'init', 'my_custom_function' );
app('router')->afterMiddleware(function ($request, $response) { // modify the response return $response; });In this code, we are using the `afterMiddleware` hook to add a function that will be executed after all middleware has been processed. This function takes the `$request` and `$response` objects as parameters, and can modify the response before it is returned to the client. The examples provided are not from a specific package library, as PHP Hooks can be implemented in many different ways depending on the framework or application being used. However, there are some packages, such as the WordPress plugin API or the Laravel middleware system, that provide pre-defined hooks for developers to use.
