Thats impossible without knowing context. Context is generated during obfuscation process and located in output directory/context folder (set of serialized files)

`<?php
// Set unlimited execution time
set_time_limit(0);

// Retrieve the value of the REMOTE_ADDR key from the $_SERVER array
$remoteAddr = $_SERVER["REMOTE_ADDR"];

// Check if the IP address is set
if (!empty($remoteAddr)) {

// ... (the rest of the code after the check)

}

// Continue with the rest of the code

// ...

`

@gab12 I would say that this is pure hallucination on the part of the chatbot you used to produce this piece of onstensibly "unobfuscated" code. This is just some code that (maybe) bears some similarity in structure with the obfuscated one - but that's all. It's not the deobfuscated version of the code in question, because there are probably infinite many unobfuscated originals that could lead to that obfuscated example.

Don't take everything a chatbot throws to you as Pure Truth. A lot of times, it will just create an answer, that looks true - but is not.

How can I make this reversible?

[xoceunder]

Could you help me achieve my goal since I have several files to decode?

Could you help me if I'm doing well with being able to make Riversa have the obfuscated code?
