My project is a combination of Java and PHP code.
The Java code is placed in a server, which is protected and other people cannot access it. But my PHP code is placed in an SD card. Data is fetched from the server and displayed on a screen.
Now I want to protect my PHP code so that no one else could view it. Is there any way to protect it? Or is there any way to lock the SD card?
After a lot of search I found Zend Guard as an appropriate solution for this problem. It helps in encryption as well as obfuscation.
