What is it?
sabre/dav is a PHP framework for building WebDAV, CalDAV and CardDAV servers. WebDAV covers file access over HTTP, CalDAV handles calendar data and CardDAV handles contact data, so developers can build a server that syncs these resources with standard clients.
The project is a library rather than a ready-to-run application, so you write a small PHP server script that wires together the components you need. Its documentation on the project website covers installation and an introduction to the framework.
The current maintained branch is 4.x, which supports PHP 7.1 and up including PHP 8.0. Older branches are listed as unmaintained.
