Silex is a simple web framework to develop simple websites based on Symfony2 components:

<?php
require_once __DIR__.'/silex.phar';

$app = new Silex\Application();

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

$app->run();

Silex works with PHP 5.3.2 or later.

Installing Silex is as easy as it can get. Download the silex.phar file and you're done!
