haXe/PHP is an extension to the haXe compiler that enables the generation of PHP code.
Why haXe/PHP? One of the biggest concerns in using haXe as a language for the server-side environment is that you need to fully control you web-server environment. This is a no go on many “cheap” (and not so cheap) shared-hosting services but PHP on the contrary is almost globally available.
Starting from version 2.01 haXe/PHP is officially part of haXe!
