支持: jdk 1.6+ (openjdk, oracle)。
目标jphp不是 zend php 引擎或facebook 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：
能够在php中使有用java对象通过 jit 和 jvm提升性能利用更好的运行时库来代替zend php的丑陋的运行时库让php不单只能用于开发web应用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, socketsenvironment architecture (like sandbox objects in runkit zend extension).gui (based on swing, improved - more flexible layouts)embedded cache system for classes and functionsoptional hot reloading for classes and functions语言支持的特性(without zend runtime libraries)

(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?
