The <info>%command.name%</info> runs PHP's built-in web server:

45+
To change the default bind address and the default port use the <info>address</info> argument:

47+
<info>%command.full_name% 127.0.0.1:8080</info>
48+

To change the default document root directory use the <info>--docroot</info> option:
50+
51+
<info>%command.full_name% --docroot=htdocs/</info>
52+
53+
If you have a custom document root directory layout, you can specify your own
54+
router script using the <info>--router</info> option:
55+

<info>%command.full_name% --router=app/config/router.php</info>

Specifying a router script is required when the used environment is not "dev" or

"prod".
