PHP include_once 在本地工作但调用 cron 不工作

Question

我使用 include_once 在 php 中包含文件，它将在本地主机中工作，但使用 cron 运行相同的文件时显示错误

File name : cron_all.php
<?php
    define('project_name','/cloud');
    include_once($_SERVER['DOCUMENT_ROOT'].project_name."/references/library.php");
?>

错误:

[root@xx-xxx-xx~]# php /var/www/html/cloud/cloud_ip_automation/cron_all.php

PHP Warning: include_once(/cloud/references/library.php): failed to open stream: No such file or directory in /var/www/html/cloud/cloud_ip_automation/cron_all.php on line 3

Warning: include_once(/cloud/references/library.php): failed to open stream: No such file or directory in /var/www/html/cloud/cloud_ip_automation/cron_all.php on line 3

PHP Warning: include_once(): Failed opening '/cloud/references/library.php' for inclusion (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html/cloud/cloud_ip_automation/cron_all.php on line 3

从 CLI 运行时未设置 $_SERVER 变量。您必须使用 dirname(__FILE__) 并使路径相对于当前文件。

例如在你的情况下，是这样的:

include_once(dirname(__FILE__).'/../'.project_name.'/references/library.php');
