RubyVM on PHP
=============

[](#rubyvm-on-php)

The RubyVM on PHP is implementation RubyVM written in PHP 100%. Completely documentation not exists how to implement RubyVM, and I was referred [Ruby source code](https://github.com/ruby/ruby) when contributing this project.

*Notice: This project is very ultra super hyper maximum experimental implementation*

*Notice: I tested Ruby version 3.2 and 3.3 only*
