Developers use this tool to protect their source code.

A: You can bypass by installing the loader (runs the script) but you cannot bypass to see source code.

Instead of modifying the core encoded files, check if the application provides a plugin architecture, hooks, or an API. You can often extend the functionality of an encrypted application by writing external, unencrypted modules that interact with it. Conclusion

echo "zend_extension = /usr/lib/php/20170718/ioncube_loader_lin_7.2.so" >> /etc/php/7.2/cli/php.ini

If the original vendor is no longer in business and you must modify the application, the safest long-term approach is to map out the inputs, outputs, and features of the encoded module and rewrite it from scratch. Developing open, modern, and documented PHP code removes dependencies on outdated loaders and ensures your application remains maintainable moving forward.
