从Crontab运行包含require_once()的PHP文件

Question

我正在尝试从crontab运行一个php文件.php的目的是简单地向用户发送电子邮件.包括我的php框架的头文件.但是crontab似乎遇到了路径问题.我已经尝试将其更改为绝对路径..请参阅下面的测试用例.

使用require_once(http://www.test.com/inc/header.php)并运行php -f test.php命令行会导致:

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

使用require_once('../../inc/header.php');并运行php -f test.php命令行会导致php文件成功执行.

但是看着我的cron标签:

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

并查看/ var/mail /中的结果,它返回此错误:

PHP Warning:  require_once(../../inc/header.php): failed to open stream: No such file or directory in /home/user/public/trybe-ing.com/public/deploy/cron/test.php on line 3
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

似乎crontab无法像从命令行运行时那样运行php文件.我怎样才能让它发挥作用？

你能看出我做错了什么并提供解决方案吗？

尝试使用__DIR__ 魔术常量包含文件的完整路径:

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

这样,它将需要它的完整路径并从任何目录工作,而不必首先更改到PHP文件的工作目录.
