php - 在 Web 服务器上执行()错误，但在本地服务器上没有错误

标签 php mysql

我的客户网站有一个商店定位器，它使用数据库来获取商店的所有信息。该商店定位器在我的台式机和笔记本电脑本地服务器(本地主机)上完美运行，但是一旦我将所有内容上传到我的测试站点，商店定位器将无法工作。在名为 locate.php 的文件中，我包含一个名为 store.php 的文件/类，当我转到本地服务器上的locate.php 文件时，我只会收到以下通知没什么大不了的。

enter image description here

当我访问我的网站时，出现此错误。

enter image description here

在 locate.php 中，我还包含一个名为 defines.php 的文件，其中包含访问数据库所需的信息(主机、用户名、密码、数据库名称)。起初我以为这可能是 GoDaddy 的问题，但我使用了 localhost 和我的网站 IP 作为主机，删除并重新上传了数据库，但似乎没有任何效果。

这是我在此线程中提到的文件。
