What is PHPJava?
================

[](#what-is-phpjava)

PHPJava is an experimental library which emulates JVM (a.k.a. Java Virtual Machine) and compiling intermediate code by PHP 🐘 And PHPJava reads binary from pre-compiled Java file(s) ☕ So, PHPJava is **NOT** bridge to Java. This library can be run 100% in PHP. This project referred to [Java Virtual Machine Specification](https://docs.oracle.com/javase/specs/jvms/se11/html/index.html) documentation at the time we made it.

We are welcoming any contributions to this project 💪

```

Quick start
-----------

[](#quick-start)

1. Install PHPJava in your project:

```
