$ _SERVER ['DOCUMENT_ROOT']在通过cron运行的php脚本中不起作用 [英] $_SERVER['DOCUMENT_ROOT'] does not work in the php script running through cron

问题描述

我使用$ _SERVER ['DOCUMENT_ROOT']。/ lib / sft_required.php;以将'sft_required'文件包含在PHP脚本中。当我使用浏览器运行这个文件，它工作正常，但当我作为cron工作作业运行它不工作。

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 running wget）访问），那么它当然不起作用。

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，因此未设置 $ _ SERVER 。

There is no server, so $_SERVER is not set.
