HipHop for PHP在技术上不是编译器本身。相反，它是一个源代码变压器。 HipHop以编程方式将您的PHP源代码转换为高度优化的C ++，然后使用g ++编译它。 HipHop以语义相等的方式执行源代码，并牺牲了一些很少使用的功能（例如eval（）），以改善性能。 HipHop包括代码转换器，PHP运行时系统的重新实现，以及许多常见PHP扩展程序的重写，以利用这些性能优化。

HipHop for PHP isn't technically a compiler itself. Rather it is a source code transformer. HipHop programmatically transforms your PHP source code into highly optimized C++ and then uses g++ to compile it. HipHop executes the source code in a semantically equivalent manner and sacrifices some rarely used features — such as eval() — in exchange for improved performance. HipHop includes a code transformer, a reimplementation of PHP's runtime system, and a rewrite of many common PHP Extensions to take advantage of these performance optimizations.

另一篇关于ReadWrite Web的文章证实了Facebook获得更快，推出本土PHP编译器和另一个由Marco Tabini 描述你需要知道的。
