How to Decode ionCube encrypted files? [closed]

I am customizing geodesic classified, my client has not given me access to a licence file (rather I have not asked him about this).

I am able to customize it from the admin panel, but I want to customize it on my local system.

But when I tried to do this it get redirected to site off page.

I think it is because of the product.php file code (I have same code as this one):

What does this PHP do? Is it an encoder/decoder?

How does ionCube work?

The tools use the technique of compiling to bytecode prior to encoding so that source code is eliminated, and runtime overheads are reduced. A PHP extension called the ionCube Loader handles the reading and execution of encoded files at run time.

How do I encrypt PHP files with ionCube?

The ionCube PHP Encoder includes an encryption option. This feature is used to protect non-PHP files (but it differs from the PHP encoding since the output isn't a bytecode format format). To encrypt files, the --encrypt command-line option is used. You can then specify a file pattern that will be encrypted.

ionCube (at least when it was PHP Accelerator) compiled PHP to bytecode prior to encoding.

This eliminates the source code entirely, and even if you were able to reverse the encoding process, you would still be left with compiled opcodes, not source.

The ionCube loader decodes the bytecode, which then does not need to be parsed, and is executed directly by the PHP virtual machine.

If I recall correctly, the encoder also performs optimisations and obfuscations on the bytecode, that help prevent decompilation.
