$_SERVER['DOCUMENT_ROOT'] does not work in the php script running through cron

Question

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.

Answer 1

you could populate the $_SERVER['DOCUMENT_ROOT'] on your own

$_SERVER['DOCUMENT_ROOT'] = dirname(__FILE__); 

if the cron file is in document root

$_SERVER['DOCUMENT_ROOT'] = dirname(dirname(__FILE__)); 

if the cron file is one directory above the document root

Answer 2

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.

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