The "Symfony Demo Application" is a reference application created to show how to develop Symfony applications following the recommended best practices.
First, install the Symfony Installer if you haven't already. Then, install the Symfony Demo Application executing this command anywhere in your system:
$ symfony demo
# if you're using Windows:
$ php symfony demo
If the demo
command is not available, update your Symfony Installer to the
most recent version executing the symfony self-update
command.
NOTE
If you can't use the Symfony Installer, download and install the demo application using Git and Composer:
$ git clone https://github.com/symfony/symfony-demo $ cd symfony-demo/ $ composer install
If you have PHP 5.4 or higher, there is no need to configure a virtual host in your web server to access the application. Just use the built-in web server:
$ cd symfony-demo/
$ php app/console server:run
This command will start a web server for the Symfony application. Now you can access
the application in your browser at http://localhost:8000. You can stop the built-in
web server by pressing Ctrl + C
while you're in the terminal.
NOTE
If you're using PHP 5.3, configure your web server to point at the
web/
directory of the project. For more details, see: http://symfony.com/doc/current/cookbook/configuration/web_server_configuration.html
