$_SERVER['DOCUMENT_ROOT'] 在通过 cron 运行的 php 脚本中不起作用
我使用 $_SERVER['DOCUMENT_ROOT']."/lib/sft_required.php";在 PHP 脚本中包含sft_required"文件.当我使用浏览器运行此文件时，它工作正常，但是当我将它作为 cron 作业运行时，它不起作用.我们通过cron运行脚本的时候好像没有包含这个文件.
I use $_SERVER['DOCUMENT_ROOT']."/lib/sft_required.php"; to include the 'sft_required' file in a PHP script. When I run this file using browser, it works fine but when I run this as a cron job job, it does not work. It seems that the file is not included when we run the script through cron.
推荐答案
假设您直接通过 cron 运行脚本(而不是从由 cronjob 触发的 HTTP 请求访问的 Web 服务器(例如通过 cron 运行 wget))，那当然不行.
Assuming you are running the script directly through cron (as opposed to from a web server accessed by an HTTP request triggered by a cronjob (e.g. by cron running wget)), then of course it doesn't work.
没有服务器，所以没有设置$_SERVER.
There is no server, so $_SERVER is not set.
