将PHP源码编译成JVM字节码的编译器：JPHP

jopen 10年前

JPHP是一个类似于javac的编译器，它能够将PHP源代码编译成JVM字节码的编译器。然后就实现了让PHP程序运行在Java虚拟机器上。 它支持许多PHP5.3+的特性。JPHP与 JRuby和Jython相似。

支持: JDK 1.6+ (OpenJDK, Oracle)。

目标

JPHP不是 Zend PHP 引擎或非死book HHVM的一个代替。它并不想实现zend运行库(比如：Curl, PRCE等)。这个项是为了：

  1. 能够在PHP中使有用Java对象
  2. 通过 JIT 和 JVM提升性能
  3. 利用更好的运行时库来代替Zend PHP的丑陋的运行时库
  4. 让PHP不单只能用于开发Web应用
  5. Also: unicode for strings and threads

特性

  • 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

语言支持的特性

(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)

还不支持什么?

  • 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)
