如果你被允许运行真正的本地二进制文件，那么这是你的编译器:

https://github.com/ircmaxell/php-compiler

这是一个用PHP编写的PHP编译器!

It compiles PHP code to its own VM code. This VM code can then either be interpreted by its own interpreter (also written in PHP, isn't that crazy?) or it can be translated to Bitcode. And using the LLVM compiler framework (clang and co), this Bitcode can be compiled into a native binary for any platform that LLVM supports (pretty much any platform that matters today). You can choose to either do that statically or each time just before the code is executed (JIT style). So the only two requirements for this compiler to work on your system is an installed PHP interpreter and an installed clang compiler.

如果您不允许运行本机二进制文件，您可以使用上面的编译器作为解释器，让它解释自己的VM代码，但是这会很慢，因为您运行的PHP解释器本身运行在PHP引擎上，因此您有“双重解释”。

phc允许你将PHP程序编译成共享库，这些库可以上传到服务器。PHP程序被编译成二进制文件。它以支持求值、包含和整个PHP标准库的方式完成。

还有bcgen (bcompiler的一个PHP7端口):

(仅PHP7.2)

PHP不像许多程序那样真正被编译。您可以使用Zend的编码器使其不可读。

自从这个问题第一次被问到，答案已经从直截了当的“不”变成了“有点”

Hip Hop for PHP是一个编译器，它将PHP代码转换为高度优化的c++ 显然，某些函数不受支持(例如' explosion ')

我在寻找更多关于如何实现HipHop的信息时发现了这个问题，我想我应该说出来:)

然而，自2013年以来，Facebook不再使用它，它已经停止使用，转而使用HHVM，这不是一个编译器:https://en.wikipedia.org/wiki/HipHop_for_PHP

Actually, the Just-In-Time compiler introduced with PHP 8 does in fact compile PHP. Strangely enough, it doesn't really speed up CMS based websites (e.g. WordPress), however, it does open the doors for PHP to compete with the likes of C++. For more information, see the RFC behind the JIT implementation here: https://wiki.php.net/rfc/jit. Also, Matthew Weir O'Phinney has posted a number of insightful blogs that shed light on its capabilities. Start reading here: https://www.zend.com/blog/exploring-new-php-jit-compiler.
