It parses your PHP code into an Abstract Syntax Tree (AST) and scrambles it. It renames variables, functions, and classes, mixes up control flow statement structures, and strips out all comments.
Historically, Zend Guard was the official protection tool created by Zend Technologies (the company behind PHP).
: These are the strongest tools for preventing casual theft, but they are not 100% foolproof. A determined attacker with a debugger can potentially intercept the code after it's decrypted in memory.
A quality obfuscator should:

When looking for a "better" obfuscator, evaluate these core pillars:
SourceGuardian is a powerful, actively maintained commercial encoder that serves as the strongest direct alternative to IonCube.
Another powerful, developer-focused open-source tool built on top of the popular Nikita Popov PHP-Parser library.

It provides maximum security against reverse engineering. It allows you to lock code to specific IP addresses, domain names, or server MAC addresses. You can also add built-in license expiration dates.
It compiles PHP source code into intermediate bytecode, which is then optimized and encrypted.
Introduction PHP powers over 75% of the web. Because it is an interpreted scripting language, its source code is deployed in plain text. Any user with server access can read, copy, modify, or steal your intellectual property.
Legacy enterprise systems and environments heavily reliant on the Zend ecosystem. 3. SourceGuardian
: A robust competitor to ionCube that integrates both obfuscation and encryption
