How is this PHP encoded?

Question

Does anybody know how this PHP code is encoded? I don\'t know whether it\'s Zend, ionCube or something else.

Answer 1

My guess is that this code uses Obfuscation.
To obfuscate a code is to transform its source to a virtually unreadable analog. It's exactly the same functionality, but variable and function names are changed in a way which would make it very hard to read.

It's a usual practice used for code which can be disassembled (like .NET or any interpreted language like PHP, Ruby, Perl), to protect it as an intellectual property.
