从Crontab运行包含require_once（）的PHP文件

Question

I'm trying to run a php file from a crontab. The aim of the php is to simply send an email to a user. Including the header files of my php framework. But the crontab seems to be having a problem with the paths. I've tried changing it to an absolute path.. see test cases below.

Using require_once(http://www.test.com/inc/header.php) and running php -f test.php to the command line results in:

PHP Warning:  require_once(): http:// wrapper is disabled in the server configuration by allow_url_include=0 in /home/user/public/test.com/public/deploy/cron/test.php on line 3
PHP Warning:  require_once(http://www.test.com/inc/header.php): failed to open stream: no suitable wrapper could be found in /home/user/public/trybe-ing.com/public/deploy/cron/test.php on line 3
PHP Fatal error:  require_once(): Failed opening required 'http://www.test.com/inc/header.php' (include_path='.:/usr/share/php:/usr/share/pear') in /home/user/public/test.com/public/deploy/cron/test.php on line 3

Using require_once('../../inc/header.php'); and running php -f test.php to the command line results in the php file being carried out successfully.

But looking at my cron tab :

*/1 * * * * php /home/user/public/test.com/public/deploy/cron/test.php

And looking at the results in /var/mail/, it returns this error:

PHP Fatal error:  require_once(): Failed opening required '../../inc/header.php' (include_path='.:/usr/share/php:/usr/share/pear') in /home/user/public/test.com/public/deploy/cron/test.php on line 3

It seems that the crontab is not able to run the php file as it would when running it from the command line. How can I get this to work?

Can you see what i'm doing wrong and offer a solution?

Try including the file with it's full path by using the __DIR__ magic constant:

require_once(__DIR__ . '/../../inc/header.php');

That way, it will be required with it's full path and work from any directory without having to change to the working directory of your PHP file first.
