我真的很挣扎。我有一个 viewdetails.php 页面、addnew.php 页面和一个 php.php。php.php 页面有我对这两个页面的查询。首先，我有在 viewdetails.php 上显示结果的查询，第二个是在 addnew.php 页面上显示结果的查询。我遇到的问题是，当我在浏览器中打开 addnew.php 时，它给了我关于 dbandpassword.php 的路径和 viewdetails.php 查询中的其他项目的错误。
如何将所有这些查询保存在一个页面 (php.php) 中并将它们分开，以免出现错误？我应该将这两个查询组合在一起还是只是其中的一部分？我知道代码需要清理，我现在并不担心。我也知道，如果将查询放在自己的文件（php.php，php2.php）中，它们都可以单独工作。
