phpinfo()和有什么不一样?和php -i? [英] What is the difference between phpinfo(); and php -i?

问题描述

搜索DDG，在这里没有得到任何有趣的结果.我听说它们是不同的，但是我想知道是什么使它们与众不同，以及具有两种不同的配置有什么优势?

编辑:是的，我都在CLI上运行它们.

解决方案

phpinfo()是一种语言功能，无论通过Web SAPI还是从CLI调用执行该脚本的脚本，它都会显示其输出；

php -i纯粹是一个命令行开关，用于从命令行获取有关PHP的信息.

为什么Web sapi和CLI的配置不同?因为您可能有不同的要求；开发人员通常会运行较长的命令行脚本，并且不希望应用Web sapi超时，这与内存设置类似；和最大文件/帖子大小ini设置对CLI毫无意义，那么为什么只在需要Web时才在cli ini文件中添加它们?

Search on DDG and in here didn't get any interesting results. I've heard they're different, but I want to know what makes them different and what advantage is there in having two different configurations ?

EDIT : Yes, I am running them both from the CLI.

解决方案

phpinfo() is a language function that will display its output regardless of whether the script that it's executed in is called through the web SAPI or from CLI;

php -i is purely a command line switch to get information about PHP from the command line.

Why different configurations for web sapi and for CLI? Because you might have different requirements; often devs will run long command line scripts and don't want the web sapi timeout applied, similarly with memory settings; and max file/post size ini settings are meaningless for CLI, so why bother having them in the cli ini file when they're only needed for the web?
