A simple script to deobfuscate PHP file obfuscated with FOPO Obfuscator - http://fopo.com.ar/
There are PHP as well as Python version of the script.
python deobfuscator.py obfuscated.php [output=deobfuscated.php]
php deobfuscator.php obfuscated.php
In this case the deobfuscated PHP code will be echo-ed because the PHP version of this script is designed to be executed online.
You can deobfuscate indeed your own obfuscated PHP file online here:
Paste the obfuscated PHP file content inside obfuscated.php file, then click Run and you will see the deobfuscated PHP code (I hope :P).
