If you try to open your sabredav webserver in a browser, you will by default be greeted by an error.
SabreDAV ships with a plugin that adds directory indexes, just like many webservers do. This makes your server a lot friendlier on the eyes when opening it with a webbrowser, and is also extremely handy for debugging.
// We assume $server is a Sabre\DAV\Server $plugin = new \Sabre\DAV\Browser\Plugin(); $server->addPlugin($plugin);
That's all. If you don't like the default style (which is a bit plain), you can extend the class and override the html generating methods.
