Using PHP from OpenHab Jetty server

I’m trying to enable the use of PHP from within the OH Jetty server.
I have read the previous thread, but when I enable the CGI servlets I too get the ClassNotFoundException.
Does anyone know what may cause this and did anyone succeed ?
Any help would be appreciated!
