How to use PHP built-in web server and disable access logging

PHP comes with an internal (built in) server which can be used as a web server for development and testing purposes.

As this is a single thread process and runs each requested PHP script sequentially, the process waits for each script to be fully executed before moving on. That's why this should not be used in a production environment with public access. This is also clearly marked on the built-in web server documentation:

This web server is designed to aid application development. It may also be useful for testing purposes or for application demonstrations that are run in controlled environments. It is not intended to be a full-featured web server. It should not be used on a public network.

The web server can be launched by using php on the command line with the -S parameter, defining the listener. An additional (optional) parameter -t can be used to set the "document root" for the web server.

ck@mintp /var/www/html $ php -S -t /var/www/html
[Mon Feb 28 09:02:38 2022] PHP 7.4.3 Development Server ( started

With each request on this web server...:

ck@mintp ~ $ curl localhost:8053

... the access to the requested path is logged:

ck@mintp /var/www/html $ php -S -t /var/www/html
[Mon Feb 28 09:02:38 2022] PHP 7.4.3 Development Server ( started
[Mon Feb 28 09:02:47 2022] Accepted
[Mon Feb 28 09:02:47 2022] [404]: (null) / - No such file or directory
[Mon Feb 28 09:02:47 2022] Closing

Of course when requesting a valid file, the (stdout) output from the web server shows this request:

ck@mintp ~ $ cat /var/www/html/echo.php
<?php echo "Hello world"; ?>

ck@mintp ~ $ curl localhost:8053/echo.php
Hello world

ck@mintp /var/www/html $ php -S -t /var/www/html
[Mon Feb 28 09:46:45 2022] PHP 7.4.3 Development Server ( started
[Mon Feb 28 09:49:22 2022] Accepted
[Mon Feb 28 09:49:22 2022] [200]: GET /echo.php
[Mon Feb 28 09:49:22 2022] Closing

But sometimes the access log is not wanted. In this case the additional -q parameter (standing for quiet) can be used:

ck@mintp /var/www/html $ php -S -t /var/www/html -q
[Mon Feb 28 09:53:35 2022] PHP 7.4.3 Development Server ( started

Only the very first (starting) line is shown in this case, no further request will be logged.
