我在EC2上有文件结构,如:但面临一些文件引用问题.

index.php
-db
  -config.php
-cron
  -cron1.php

我尝试过文件引用:

`require_once (dirname(__FILE__).'/db/config.php');`
`require_once (($_SERVER['DOCUMENT_ROOT']).'/db/config.php');`

但是cron没有run.it在邮件中给出错误

`PHP Warning:  require_once(/db/config.php): failed to open stream: No such file or directory in /var/www/html/cron/cron1.php on line 3

Warning: require_once(/db/config.php): failed to open stream: No such file or directory in /var/www/html/cron/cron1.php on line 3

PHP Fatal error:  require_once(): Failed opening required '/db/config.php' (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html/cron/cron1.php on line 3

Fatal error: require_once(): Failed opening required '/db/config.php' (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html/cron/cron1.php on line 3`

我正在创建 RESTful Web 服务，但我想保护这些 Web 服务并希望授予对特定域名的访问权限。我通过以下 PHP 代码实现了这一点：

 $allowed_hosts = array("domain1.com", "domain2.com", "domain3.com");

  if (!in_array(strtolower($_SERVER["HTTP_HOST"]), $allowed_hosts))
   die ("Unknown host name ". $_SERVER["HTTP_HOST"]);

我想知道这是限制访问的正确方法吗？
