# PHP Built in server

Learn how to use the built in server to develop and test your application without the need of other tools like xamp, wamp, etc.

# Running the built in server

php -S localhost:80

PHP 7.1.7 Development Server started at Fri Jul 14 15:11:05 2017
Listening on [http://localhost:80](http://localhost:80)
Document root is C:\projetos\repgeral

This is the simplest way to start a PHP server that responds to request made to localhost at the port 80.

The -S tells that we are starting a webserver.

The localhost:80 indicates the host that we are answering and the port. You can use other combinations like:

mymachine:80 - will listen on the address mymachine and port 80;
127.0.0.1:8080 - will listen on the address 127.0.0.1 and port 8080;
