Slim is a PHP micro framework that helps you quickly write simple yet powerful web applications and APIs.

use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;

require 'vendor/autoload.php';

$app = new \Slim\App;
$app->get('/hello/{name}', function (Request $request, Response $response, array $args) {
    $name = $args['name'];
    $response->getBody()->write("Hello, $name");

    return $response;

Download & Install

We recommend you install the Slim Framework with the Composer dependency manager.

The easiest way to start working with Slim is to create a project using Slim-Skeleton as a base by running this bash command:

$ php composer.phar create-project slim/slim-skeleton [my-app-name]

Replace [my-app-name] with the desired directory name for your new application.

You can then run it with PHP's built-in webserver:

$ cd [my-app-name]; php -S localhost:8080 -t public public/index.php


HTTP Router

Slim provides a fast and powerful router that maps route callbacks to specific HTTP request methods and URIs. It supports parameters and pattern matching.


Build your application with concentric middleware to tweak the HTTP request and response objects around your Slim app.

PSR-7 Support

Slim supports any PSR-7 HTTP message implementation so you may inspect and manipulate HTTP message method, status, URI, headers, cookies, and body.

Dependency Injection

Slim supports dependency injection so you have complete control of your external tools. Use any Container-Interop container.
