推荐答案

看看 exec 系统等： http：/ /www.php.net/manual/en/book.exec.php

显然，如果你打算使用 sudo 对于根访问的东西（不推荐），那么你需要提供一个密码以某种方式或设置PHP运行的用户不需要密码。

Obviously, if you are going to use sudo for root access stuff (not recommended) then you would need to either supply a password somehow or set the user which PHP is running as to not require a password.

可能最好使用 SSH 调用，并提供通过该命令执行的命令。

It may be better to use an SSH call for this and supply the command to execute via that command.

总之，我真的不建议使用PHP（或任何语言）来运行一系列命令，然后使用 sudo

To sum up, I really don't recommend using PHP (or any language for that matter) to run a series of commands which then uses sudo
