slim/slim 3.9.1

Slim/Slim is a PHP micro-framework that immensely simplifies the process of building powerful web applications and APIs. Its minimalistic architecture and rich features make it ideal for rapidly creating robust applications and APIs with PHP.

To utilize Slim/Slim, you should first install it through Composer, a tool for managing dependency in PHP. You can install Slim and all its necessary dependencies by running composer require slim/slim in the command line. Slim requires PHP 7.4 or newer.

Once installed, you can start using Slim for building your web applications or APIs. Here is a basic example of how to setup a simple 'Hello World' application using Slim:

<?php
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\Factory\AppFactory;

require __DIR__ . '/../vendor/autoload.php';

$app = AppFactory::create();
$app->addErrorMiddleware(true, true, true);

$app->get('/', function (Request $request, Response $response) {
    $response->getBody()->write('Hello World');
    return $response;
});

$app->run();

In this example, a GET route for the root URL / is defined. When you access the root URL, it will display 'Hello World'. Remember to run this script with a suitable web server environment, like Apache or NGINX.

After writing your own routes and functions, you can test your application using built-in PHP server by running php -S localhost:8000 -t public from your project directory.

For a more comprehensive guide on using Slim/Slim, refer to the official Slim Framework documentation. It can be found at https://www.slimframework.com/docs/v4/start/installation.html. The documentation provides a detailed guide for installing, configuring, and getting up to speed with using the Slim framework to build PHP applications and APIs.
