因为你说的是​​ powershell，所以我假设是 Windows.你可以在windows上安装php，但这也意味着安装apache或启用IIS.

I'm assuming windows since you said powershell. You can just install php on windows but that means also installing apache or enabling IIS.

或者显然有一个内置网络服务器用于命令-线功能，可以最大限度地减少配置这些东西所涉及的麻烦.

Or there's apparently a built-in webserver for command-line functionality that might minimize the amount of headache involved in configuring that stuff.
