mod_php和cgi php脚本之间有什么区别？

What are the differences between mod_php and cgi php script?

我的意思是，为什么使用mod_php而不是简单的php脚本来运行它们会更好（是吗？）

I mean, why it's better (is it?) to use mod_php instead simple php scripts, running them as CGIs?

谢谢

推荐答案

使用CGI时：PHP进程由Apache启动，它是解释PHP代码的PHP进程，而不是Apache 本身。

When using CGI : a PHP process is launched by Apache, and it is that PHP process that interprets PHP code -- not Apache itself.

从理论上讲，一种独特的PHP必须为每个请求创建流程-这会使事情变慢：Apache还要做更多工作来回答请求。

（好吧，正如@ AlReece45在评论中指出的那样，使用FastCGI可以使它更好）

In theory, a distinct PHP process has to be created for each request -- which makes things slower : Apache has more work to do to answer a request.
(Well, as pointed out by @AlReece45 in a comment, this can be made better using FastCGI)

将PHP用作Apache模块（ mod_php 或 mod_php5 ），PHP解释器在Apache进程内部有点 嵌入式：没有外部PHP进程。

When using PHP as an Apache module (mod_php, or mod_php5), the PHP interpreter is kind of "embedded" inside the Apache process : there is no external PHP process.

这意味着：

• 无需分叉（更快）


• Apache和PHP之间的更好通信

一般来说，我会说 mod_php 是最常用的解决方案。

Generally speaking, I would say that mod_php is the solution that's used the most.
