php 作为解释语言或编译语言
可能的重复：
PHP 是编译还是解释？
我对 PHP 使用的单词有点困惑。我知道PHP是一种脚本语言。有时我读到它是解释的，有时它是编译的！
怎么办？，这是否与它作为 Apache 模块安装时被编译有关，如果它作为 CGI 安装时它将被解释...但我知道有人用来告诉我 PHP 也是解释语言.. 我可能听起来很愚蠢，
但目前，我很困惑。我很清楚编译器和解释器之间的区别。

Is PHP compiled or interpreted?
I am little confused with the words used with PHP. I know PHP is a scripting language. Some times I read it is interpreted or some time it is compiled!
How?, Is it something to do with when it is installed as Apache module it is compiled and if it is installed as CGI then it will be interpreted... But I know someone use to tell me that PHP is interpreted language too...
I may sound stupid but Currently, I am quite confused .I am quite aware of difference between compiler and interpreter.

通常，PHP 是一种解释性语言。解释器在运行时读取并评估脚本。它没有被预编译成不同的形式。
有一些 PHP 编译器，有些实际上编译它们，有些只是将脚本与解释器一起打包/混淆成独立的可执行文件。

Typically, PHP is an interpreted language. The script is read and evaluated at run-time by the interpreter. It is not pre-compiled into a different form.
There are PHP compilers, some which actually compile them, and some which just package/obfuscate the script along with the interpreter into a self-standing executable.

PHP 是一种解释性语言。解释 PHP 的二进制文件是被编译的，但你编写的代码是被解释的。检查有关 PHP 的 wiki 页面
The PHP is an interpreted language. The binary that interprets PHP is compiled, but the code you write is interpreted. Check the wiki page on PHP
