Bespoke PHP Obfuscation Tool

I'm in need of a specialized PHP obfuscator that can handle some key requirements.

- Compatible with Various PHP Frameworks: The obfuscator should be able to work seamlessly with popular PHP frameworks like Laravel, CodeIgniter, and Symfony. This ensures it can be integrated easily into existing projects built on these frameworks (not obfuscating 1 by 1 every php file)

- Advanced Obfuscation Techniques: I require the tool to support variable renaming. This feature is crucial for enhancing code security by making it harder for potential attackers to interpret the code's logic.

- String Encoding: The obfuscator should encode only critical strings. By encoding these strings, the tool can add an extra layer of security to the application without impacting its functionality.

Ideal Skills:
- Proficient in PHP and familiar with various PHP frameworks.
- Experience in developing obfuscators or similar security tools.
- Knowledge of encryption and encoding techniques.
- Strong understanding of code security practices.
