##背景
HHVM 其前身是hiphop(hphpc)，进行php代码->cpp代码->二进制的转换，这个引擎属于静态编译优化，在Facebook应用了4年（2007-2011），但是由于开发、编译、调试、维护并不方便，所以2011年12月Facebook 开始了HHVM的开发和调研；
也就是hiphop->hphpi->hhvm的一个发展。

1. HipHop PHP: 将PHP代码翻译成C++代码，然后编译成二进制运行
1. hphpi: 为了解决编译太慢的问题，实现的一个PHP解释器，不过代码和hphpc很多都不一样，有很多的问题
1. HHVM：一个真正的虚拟机，目标是和Zend VM保持兼容。
