PHPJava is able to become a JVM language with PHP syntax. This feature analyze to AST using nikic/php-parser, And PHPJava assemble a intermediately code with assembler in PHPJava, and you can run it as a JVM language with java command. This feature is a experimental implementation more than any other.

1. Create HelloWorld.php

<?php
class HelloWorld
{
    public static function main(array $strings)
    {
        echo "Hello World!";        
    }
}

2. To run PackageAssembler, and assemble an intermediately code.

<?php 
use PHPJava\Compiler\Lang\PackageAssembler;
use PHPJava\Compiler\Lang\Stream\FileStream;

(new PackageAssembler(
    (new FileStream(__DIR__ . '/HelloWorld.php'))
        // Specify output directory after compile is finished.
        ->setDistributeDirectory(__DIR__ . '/dist')
))->assemble();

3. To run generated HelloWorld.class in dist directory.

$ cd dist
$ java HelloWorld

You'll get Hello World!.

This feature compile as the JDK 8.

PHPJava will try to convert to a string when passed literal or object is not a string. For example, The number literal 1 will convert as below roughly on Java.

int number = 1;
(new java.lang.Integer(number)).toString()

PHPJava will assemble operation code as follows:

 0: iconst_1
 1: istore_1
 2: getstatic     #21                 // Field java/lang/System.out:Ljava/io/PrintStream;
 5: new           #9                  // class java/lang/Integer
 8: dup
 9: iload_1
10: invokespecial #7                  // Method java/lang/Integer."<init>":(I)V
13: invokevirtual #13                 // Method java/lang/Integer.toString:()Ljava/lang/String;
16: invokevirtual #25                 // Method java/io/PrintStream.print:(Ljava/lang/String;)V

PHPStandard is a namespace for runtime classes of PHP.
