Warning: You are browsing the documentation for Symfony 2.3, which is no longer maintained.
Read the updated version of this page for Symfony 6.0 (the current stable version).
Since PHP 5.4 the CLI SAPI comes with a built-in web server. It can be used to run your PHP applications locally during development, for testing or for application demonstrations. This way, you don't have to bother configuring a full-featured web server such as Apache or Nginx.
The built-in web server is meant to be run in a controlled environment. It is not designed to be used on public networks.
Running a Symfony application using PHP's built-in web server is as easy as
$ php app/console server:run
This starts a server at
localhost:8000 that executes your Symfony application.
The command will wait and will respond to incoming HTTP requests until you
terminate it (this is usually done by pressing Ctrl and C).
By default, the web server listens on port 8000 on the loopback device. You can change the socket passing an IP address and a port as a command-line argument:
$ php app/console server:run 192.168.0.1:8080
The built-in web server expects a "router" script (read about the "router"
script on php.net) as an argument. Symfony already passes such a router
script when the command is executed in the
prod or in the
--router option in any other environment or to use another router
$ php app/console server:run --env=test --router=app/config/router_test.php
If your application's document root differs from the standard directory layout,
you have to pass the correct location using the
$ php app/console server:run --docroot=public_html
