Unlike compiled languages (C/C++), PHP scripts are distributed in plaintext. This exposes proprietary algorithms, database credentials, and business logic to end-users. Obfuscation attempts to raise the bar for reverse engineering. However, malicious actors exploit the same techniques to evade antivirus and manual code review. Understanding both defensive and offensive obfuscation is essential for security professionals.
