问题描述

PHP是否有Java之类的虚拟机?

Does PHP have a virtual machine like Java?

推荐答案

是.

与运行PHP的平台无关，这些脚本被编译为相同的字节码，并由Zend Engine运行.

Independently from the platform PHP is running on, the scripts are compiled into the same bytecode and run by the Zend Engine.

与Java的区别在于，该编译后的代码通常不存储在单独的文件中，并且每次执行时都会重新编译脚本(但是，请参阅操作码缓存).

The difference from Java is that this compiled code is usually not stored into separate files and the scripts are re-compiled on each execution (however, see opcode caches).
