从Crontab运行包含require_once（）的PHP文件， [英] Running a PHP file from Crontab that includes require_once()

问题描述

我试图从crontab运行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似乎有路径的问题。我已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 /inc/header.php）并运行 php -f test.php 到命令行，结果：

PHP警告：require_once（）：http：//在/home/user/public/test.com/中的服务器配置中，allow_url_include = 0禁用了wrapper public / deploy / cron / test.php on line 3
PHP警告：require_once（http://www.test.com/inc/header.php）：无法打开流：没有找到合适的包装器/home/user/public/trybe-ing.com/public/deploy/cron/test.php on line 3
PHP致命错误：require_once（）：无法打开必须'http://www.test.com /inc/header.php'（include_path ='。：/ usr / share / php：/ usr / share / pear'）在/home/user/public/test.com/public/deploy/cron/test.php第3行


使用 require_once（'../../ inc / header .php'）; 并且在命令行中运行 php -f test.php 会导致php文件成功执行。

但是看看我的cron标签：

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

查看/ var / mail /中的结果，会返回以下错误：

似乎crontab不能运行php文件将从命令行运行它。

您能看到我做错了，并提供解决方案吗？

解决方案

尝试使用 __ DIR __ 魔术常量：

  require_once（__ DIR__。'/../../inc/header.php'）; 
  

这样，它将需要它的完整路径和工作从任何目录，您的PHP文件的工作目录。

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:

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?

解决方案

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.
