JPHP is a new implementation for PHP which uses the Java VM. It supports many features of the PHP language (5.3+). How does it work? JPHP is a compiler like javac, it compiles php sources to JVM bytecode and then can execute the result on the Java VM.

Supports: JDK 1.6+ (OpenJDK, Oracle)

JPHP is not a replacement for the Zend PHP engine or Facebook HHVM. We don’t plan to implement the zend runtime libraries (e.g. Curl, PRCE, etc.) for JPHP. Our project started October 2013. There was a few reasons for that:

1. Ability to use java libraries in PHP
2. Upgrading performance via JIT and JVM
3. Replacing the ugly runtime library of Zend PHP with a better runtime library.
4. Using the PHP language not only on the web
5. Also: unicode for strings and threads

• JIT (2x - 10x faster PHP 5.4)
• Optimizer (constant expressions, inline functions, etc.)
• Using java libraries and classes in PHP code.
• Unicode for strings (UTF-16, like in Java)
• Threading, Sockets
• Environment architecture (like sandbox objects in runkit zend extension).
• GUI (based on Swing, improved - more flexible layouts)
• Embedded cache system for classes and functions
• Optional Hot Reloading for classes and functions

(without zend runtime libraries)

• PHP 5.2+ fully support (with OOP)
• Closures (PHP 5.3), auto-binding $this in closures (PHP 5.4)
• Namespaces fully support (PHP 5.3)
• Spl autoloading for classes (PHP 5.3)
• Iterators, ArrayAccess, Serializable
• Type hinting for classes, arrays, callable (PHP 5.4)
• Array short syntax (PHP 5.4)
• Ternary short cut "?:", NOWDOC, __callStatic, __invoke (PHP 5.3)
• Late static binding (PHP 5.3)
• GC for cyclic references (PHP 5.3)
• Class::{expr}(), (new Foo)->bar() (PHP 5.4)
• Try finally (PHP 5.5)
• Array and string literal dereferencing (PHP 5.5)
• __debugInfo for var_dump (PHP 5.6)
• Function array dereferencing has been added, e.g. foo()[0] (PHP 5.4)
• Constants can be declared outside a class using the const keyword. (PHP 5.3)
• Dynamic access to static methods (PHP 5.3)
• Exceptions can be nested (PHP 5.3)
• ::class system constant (php 5.5)

What does not yet support?

• Traits (php 5.4)
• Generators (php 5.5)
• Goto (php 5.3)
• list() in foreach (php 5.5)
• Binary number format, e.g. 0b001001101 (php 5.4)

What non-php features does JPHP support?

• In the __toString method you can use exceptions
• Type hinting for scalars - int, double, number, string, bool, mixed, scalar (in JPHP mode)

<dependency>
    <groupId>ru.regenix</groupId>
    <artifactId>jphp-core</artifactId>
    <version>0.4-SNAPSHOT</version>
</dependency>

And add our maven repository:

<repository>
    <id>DevelNext Repo</id>
    <url>https://maven.develnext.org/repository/snapshots/</url>
</repository>

(!) At present we recomend you to use snapshot versions because the stable version is updated rarely.

• Java 1.6+ (OpenJDK or Oracle)
• Gradle 1.4+ (https://www.gradle.org/)

Before using with CLI, you should build the CLI version of the JPHP engine. To do that, use the gradle jar command:

cd /path/to/jphp_sources/jphp-cli
gradle jar

cd build/libs
jphp -v // must show version of JPHP

The result of building will be located at jphp-cli/build/libs. There will appear a few files - jphp-cli.jar, jphp.bat, jphp and you can use the jphp command in your console like this:

jphp -f /path/to/script.php

Use the php.runtime.launch.Launcher class as the Main class for your jar. By default, the launcher loads the JPHP-INF/launcher.conf configuration from a resource directory, inside this file you can specify the name of a bootstrap php file (which will be loaded from a resource directory and executed):

bootstrap.file = bootstrap.php

We have created an example project which is located in the jphp-example-project directory. To try it, you should use Gradle build system and several tasks: exampleStart or jar to build the project to a jar file which you can execute by using Java VM. By default, all jar files will be created in build/libs/.

You can use our extension jphp-swing to write GUI programs for Linux/Windows/MacOS. There is an example of GUI usage in jphp-example-project. To try it you should change the value of the bootstrap.file option in JPHP-INF/launcher.conf:

bootstrap.file = bootstrap_gui.php

It means that at first the Launcher will load the bootstrap_gui.php file from a resource path. In our case, it will be the jphp-example-project/src/main/php/bootstrap_gui.php, source of this file is simple and clear:

<?php
namespace {

    use php\lang\System;
    use php\lang\Thread;
    use php\swing\SwingUtilities;
    use php\swing\UIForm;
    use php\swing\UIManager;
    use php\swing\UIProgress;

    UIManager::setLookAndFeel(UIManager::getSystemLookAndFeel());

    SwingUtilities::invokeLater(function(){
        $form = new UIForm();
        $form->size = [500, 500];
        $form->moveToCenter();
        $form->visible = true;

        $p = new UIProgress();
        $p->size = [300, 40];
        $p->position = [100, 100];
        $p->value = 50;
        $form->add($p);

        $form->on('windowClosing', function(){
            System::halt(0);
        });
    });
}

Это компилятор и движок для языка PHP под Java VM. Он полностью работает на Java, исходный код php компилируется в байткод JVM, который подвергается оптимизациям и JIT. Если вы знакомы с проектами JRuby, Jython и т.д., то JPHP это тоже самое, только для PHP. Поддерживаются все фичи PHP 5.3+ и некоторые из PHP 5.4 и PHP 5.5.

Основное отличие от PHP это отказ от использования несогласованных runtime библиотек и расширений. Язык тот же, а библиотеки для него другие, с использованием ООП и т.д.

Больше информации о разработке вы найдете по следующим ссылкам:

На данный момент вы можете собрать JAR файл с исходниками php, который будет выполняться с помощью JPHP. Загляните в папку jphp-example-project, этот проект можно собрать в выполняемый jar файл, который можно запустить по двойному клику в Windows если у вас установлена Java. Для этого вам нужен Gradle, чтобы собрать программу используйте стандартную команду gradle jar или если хотите сразу посмотреть результат jphp-example-project выполните gradle exampleStart.

К тому же проект для примера настраивается через файл resources/JPHP-INF/launcher.conf, где можно поменять bootstrap.file на другой файл (например bootstrap_gui.php, bootstrap_server.php - это различные независимые примеры программ на JPHP).
