问题
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:
Message 23:

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?

回答1:
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.

Another way would be changing your crontab to
*/1 * * * * cd /home/user/public/test.com/public/deploy/cron && php test.php
