How to Use PHP’s built-in Web Server
How to Use PHP’s built-in Web Server¶
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.
Starting the Web Server¶
Running a Symfony application using PHP’s built-in web server is as easy as
$ php bin/console server:start
This starts the web server at
localhost:8000 in the background that serves
your Symfony application.
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 bin/console server:start 192.168.0.1:8080
You can use the
--force option to force the web server start
if the process wasn’t correctly stopped (without using the
$ php bin/console server:start --force
You can use the
server:status command to check if a web server is
listening on a certain socket:
1 2 3
$ php bin/console server:status $ php bin/console server:status 192.168.0.1:8080
The first command shows if your Symfony application will be server through
localhost:8000, the second one does the same for
Some systems do not support the
server:start command, in these cases
you can execute the
server:run command. This command behaves slightly
different. Instead of starting the server in the background, it will block
the current terminal until you terminate it (this is usually done by
pressing Ctrl and C).
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 bin/console server:start --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 bin/console server:start --docroot=public_html
Stopping the Server¶
When you are finished, you can simply stop the web server using the
$ php bin/console server:stop
Like with the start command, if you omit the socket information, Symfony will
stop the web server bound to
localhost:8000. Just pass the socket information
when the web server listens to another IP address or to another port:
$ php bin/console server:stop 192.168.0.1:8080
