The "Symfony Demo Application" is a reference application created to show how to develop applications following the Symfony Best Practices.

• PHP 7.1.3 or higher;
• PDO-SQLite PHP extension enabled;
• and the usual Symfony application requirements.

Download Symfony to install the symfony binary on your computer and run this command:

$ symfony new --demo my_project

Alternatively, you can use Composer:

$ composer create-project symfony/symfony-demo my_project

There's no need to configure anything to run the application. If you have installed Symfony, run this command and access the application in your browser at the given URL (https://localhost:8000 by default):

$ cd my_project/
$ symfony serve

If you don't have the Symfony binary installed, run php -S localhost:8000 -t public/ to use the built-in PHP web server or configure a web server like Nginx or Apache to run the application.

Execute this command to run tests:

$ cd my_project/
$ ./bin/phpunit
