“php_sapi=cli”中PHP_SAPI是用来判断是使用命令行还是浏览器执行的,如果“PHP_SAPI==’cli’”则表示是在命令行下执行。

php_sapi = cli是什么意思?

PHP常量PHP_SAPI与函数php_sapi_name()简介,PHP运行环境检测

PHP_SAPI 用来判断是使用命令行还是浏览器执行的,如果 PHP_SAPI==’cli’ 表示是在命令行下执行

php判断解析php服务是由那种服务器软件,是采用那种协议 直接输出即可

代码如下:

<?php
echo PHP_SAPI;
?>
Copy after login

我的测试环境是nginx+fastcgi 输出结果为:

cgi-fcgi
Copy after login

如果是apache 运行环境,输出结果为

apache2handler
Copy after login

如果是命令行的形式执行,结果为cli,这就是PHP_SAPI

php_sapi_name() 是用来检测PHP运行环境的函数。

该函数返回一个描述PHP与WEB服务器接口的小写字符串。

返回描述 PHP 所使用的接口类型(the Server API, SAPI)的小写字符串。

例如,CLI 的 PHP 下这个字符串会是 “cli”,Apache 下可能会有几个不同的值,取决于具体使用的 SAPI。

以下列出了可能的值:

aolserver、apache、 apache2filter、apache2handler、 caudium、cgi (直到 PHP 5.3), cgi-fcgi、cli、 continuity、embed、 isapi、litespeed、 milter、nsapi、 phttpd、pi3web、roxen、 thttpd、tux 和 webjames。

SAPI: 服务器端API,貌似和CGI是一个东西。每个服务器提供的API可能不同,但是他们都提供了CGI。

所以可以理解CGI是每个服务器都应该有的SAPI。apache有自己的SAPI,IIS也有自己的。但是php能在这些不同的服务器端工作,因为php支持了它们各自的SAPI。

PHP-CLI: php命令行接口,php可以工作在这种模式下也可以CGI模式。是SAPI的一种,它和CGI提供的功能差不多。

如何判断PHP的运行环境?

阅读ci代码过程中发现,处理URI会根据php的运行环境进行不用处理。

那么如何判断php的运行环境呢?

我们一般情况下,都是在apache下面运行我们的php程序,当然也有些人是用IIS环境的。

我们要是想知道我们目前运行的环境是什么的话,那我们可以用函数php_sapi_name()来测试,

代码:

         <!--?php <br ?--> 
         echo 
          php_sapi_name();
        
 
         ?&gt;
Copy after login

        

在apache环境下面输出的结果是“apache2handler”;

在cgi模式下输出的结果是“cgi-fcgi”

要是在命令行模式下面运行的话,那么输出的结果是:”cli”

依据这个内容我们可以判断当前运行的环境是什么!

那么在命令行下怎么运行呢?

如下:

进入DOS 进入php.exe文件的地址 如我的是:d:/wamp/bin/php/php5.3.3/

然后输入php.exe “文件的绝对路径” 如:>php.exe d:/wamp/www/info.php

就可以了。
