如何在 根用户 （具有所有权限）而不是 没人 用户（php默认用户）下从PHP运行bash脚本？

在sudo visudo之后，多数民众赞成在我的输出：

Defaults        env_keep += "LINES COLUMNS"
Defaults        env_keep += "LSCOLORS"
Defaults        env_keep += "SSH_AUTH_SOCK"
Defaults        env_keep += "TZ"
Defaults        env_keep += "DISPLAY XAUTHORIZATION XAUTHORITY"
Defaults        env_keep += "EDITOR VISUAL"
Defaults        env_keep += "HOME MAIL"
