Homepage - Silex - The PHP micro-framework based on the Symfony Components

As of June 2018, Silex is not maintained anymore. Use Symfony 4+ instead. Read more on Symfony's blog.

Silex is a PHP microframework for PHP. It is built on the shoulders of Symfony and Pimple and also inspired by sinatra.

A microframework provides the guts for building simple single-file apps. Silex aims to be:

Concise: Silex exposes an intuitive and concise API that is fun to use.
Extensible: Silex has an extension system based around the Pimple micro service-container that makes it even easier to tie in third party libraries.
Testable: Silex uses Symfony's HttpKernel which abstracts request and response. This makes it very easy to test apps and the framework itself. It also respects the HTTP specification and encourages its proper use.

Documentation

In a nutshell, you define controllers and map them to routes, all in one step:

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

$app = new Silex\Application();

$app->get('/hello/{name}', function($name) use($app) {
    return 'Hello '.$app->escape($name);
});

$app->run();

All that is needed to get access to the Framework is to include the autoloader.

Next we define a route to /hello/{name} that matches for GET requests. When the route matches, the function is executed and the return value is sent back to the client.

Finally, the app is run. It's really that easy!
