PHP deobfuscator

[object0]

Hi everyone.
A couple years ago I was very passionate about PHP/JS decoding and reverse engineering in general. I made more than 40 (private) decoders in 2012 just for academic purposes (I love challenges, you know). After becoming a father for first time I left the scene.

My current job is related to web development, security audit, malware analysis, etc. I realize that digging into obfuscated PHP code is PITA that's why I made my own PHP deobfuscator, see screenshot.

obfuscated:

PHP Code:

<?php        

$fff = "flock";        
if ($fff($aaa, LOCK_EX)) {
    $fff($aaa, LOCK_UN);
}

function aaa() {
    $fff2 = "fget";        
    if ($fff2($aaa, LOCK_EX)) {
        $fff2($aaa, LOCK_UN);
    }
} 


deobfuscated:

PHP Code:

<?php

if (flock($aaa, LOCK_EX)) {
    flock($aaa, LOCK_UN);
}
function aaa()
{
    if (fget($aaa, LOCK_EX)) {
        fget($aaa, LOCK_UN);
    }
}

Does anyone already have success with similar tools?
