How to protect PHP code?

Hi friends,

I am working on magento ecommerce and I have tried to write some magento extension. There is an issue that I am worry about is how to encode the PHP code?

Is there any solution for this?

Thanks!

If you don’t want to plunk $$$ for the full version for an encoder (zend, ioncube, sourceguardian, etc), ioncube has an online encoder that will encode your code for a small fee.
