I need to have a licence facility on my web site

Question

Hi I have a web site on my server that is used to plan events, authorised users log in and use the site. I am in the process of selling the facility to a client 'on licence' But he wants the code/script on his server. Can anyone suggest a suitable way to go about protecting my code even if it is running on somebody else's server ? any pointers to articles etc would be much appreciated ..

thanks

Zend has some 'encryption' software for PHP: Zend Encoder, IIRC.

Now called Zend Guard apparently. There's a tutorial on their website. Alternatively try IonCube.

A quick google said there were lots of alternatives ("php encoder" will bring them up), things have changed since I last looked! there must be quite a market for PHP encoding.
