Hi everyone,

I produced a PHP web app for a client some months back that is hosted on their own server.

I have still not been paid for this work, and they are giving me the runaround.

It turns out that I still have remote admin access to their server, so I can make code changes. What I was thinking of doing was to move the core kernel off-site onto one of my own servers, and program in some kind of callback or include that gets the kernel (critical functions) from my server. Give it two weeks or so for their backups to catch this change, and then pull the plug and exercise leverage. If I do this, they will pay immediately, because the site is a critical one for a very large and influential client of theirs.

What is the most effective and easiest way of doing this? What code do I use?

Thanks for any pointers.
