Best php encoder

Hi All,

Im looking for the best and easiest php encoder.

We have developed an application here which we would love to encrypt.

I'm open to ideas, Haven't got a budget set.

Items I like are being able to restrict to an ip address.

As we are doing many updates, I don't want it to be a timely process either every time we update a file.

Any ideas would be great.

You can use NuSphere to encode your php application

I have used Zend Guard ( and never had a problem.

Regarding this, "As we are doing many updates, I don't want it to be a timely process either every time we update a file."

If you're distributing software, you probably want to have fairly sturdy version control.

You can use a unique, random key assigned to each license, and use it to "call home" with the IP address.  If the key and address do not match your expectations, you can log the event for further investigation, and even send back a "die" signal.  This is a very simple REST service.  But before you do the latter, be careful about the risk of consequential damages.  Here is what could happen.

Your client has a valid, paid license and runs the software in a hosted account.  One day, the host moves his application from server A to server B.  The new IP address causes his system to fail, neither he nor the host can figure out why, his system is down for hours, he loses hundreds of thousands of dollars, his clients abandon him, and he sues you for negligence.  I think that risk is not worth it.  Instead, just look at your logs (you can automate the inspection) and if you see hits coming from a new IP address, apply some human intelligence to the problem.

Best regards, ~Ray

I think Zend Guard and NuSphere are the best suggestions for obfuscating your code.  They are what I see most often.  Good luck with your project, ~Ray
