Nope. You want to execute arbitrary PHP code on your server, so there
is no way of "avoiding danger or hacking"... The only half-safe
solution I can think of is that the PHP server on which the user-
supplied code runs is virtual (so whatever damage the hackers do will
disappear when the server is restarted) and separate from the server
on which the application is hosted.
