This snippet of code is syntactically valid in both PHP and Java, and produces the same output in both.

PhpJava.java

/*<?php
//*/public class PhpJava { public static void main(String[] args) { System.out.printf("/*%s",
//\u000A\u002F\u002A
class PhpJava {
    static function main() {
        echo(//\u000A\u002A\u002F
        "Hello World!");
}}
//\u000A\u002F\u002A
PhpJava::main();
//\u000A\u002A\u002F

PhpJava.php

/*<?php
//*/public class PhpJava { public static void main(String[] args) { System.out.printf("/*%s",
//\u000A\u002F\u002A
class PhpJava {
    static function main() {
        echo(//\u000A\u002A\u002F
        "Hello World!");
}}
//\u000A\u002F\u002A
PhpJava::main();
//\u000A\u002A\u002F
