i would like to have an manual for the builtin webserver of php: http://php.net/manual/en/features.commandline.webserver.php
You may want to take a look at my li3_server plugin! Note that this requires 5.4 to run and Lithium is 5.3+
Someone else is going to have to write this and submit a pull request, since I haven't compiled 5.4 yet.
I've added support for the builtin webserver to the framework distro:
And the installation page has been rewritten to take advantage of it in order to simplify setup. It is assumed that people nowadays are on 5.4 for their dev environment at a minimum. Other webservers are still supported for installation via the webservers page.
