POST

Use the Slim application’s post() method to map a callback function to a resource URI that is requested with the HTTP POST method.

<?php
$app = new \Slim\Slim();
$app->post('/books', function () {
    //Create book
});

In this example, an HTTP POST request for “/books” will invoke the associated callback function

The first argument of the Slim application’s post() method is the resource URI. The last argument is anything that returns true for is_callable(). Typically, the last argument will be an anonymous function.
