PHP Code Obfuscation vs PHP Bytecode Encoding

Not all PHP protection methods are created equal. Understand the fundamental differences between source text obfuscation, userland string eval encryption, and native Zend Engine bytecode encoding.

Comparing Protection Techniques

1. Code Obfuscation

Text Transformation

Renames variables and functions to random characters (e.g., $O00_O0O), strips comments, and compresses whitespace.

⚠️ Code is still valid PHP text and can be reconstructed using automated AST formatters.

2. Eval Encryption

Userland eval() Wrappers

Encodes PHP strings using Base64/Gzip and decrypts them at runtime with PHP's built-in eval() statement.

⚠️ Vulnerable to function override hooks and PHP debugger inspection.

3. Native Encoding

Zend Engine Bytecode

Compiles PHP into binary payloads executed exclusively by a native C loader extension directly in memory.
