phpVirtualBox is an open source, AJAX implementation of the VirtualBox user interface written in PHP. As a modern web interface, it allows you to access and control remote VirtualBox instances. phpVirtualBox was created for people who prefer not to have to log in to their headless VirtualBox host to administer their virtual machines.
phpVirtualBox requires that vboxwebsrv (a program distributed with VirtualBox) is running on the VirtualBox host. It also requires a web server with PHP >= 5.2.0 installed in order to run.
