Why do I get that Error when I use include_once:
为什么在使用 include_once 时会出现该错误：
include_once("/PoliticalForum/headerSite.php");
采纳答案by Daren Chandisingh
It's because you have included a leading /in your file path. The /makes it start at the top of your filesystem. Note: filesystempath, not Web site path (you're not accessing it over HTTP). You can use a relativepath with include_once(one that doesn't start with a leading /).
这是因为您/在文件路径中包含了前导。这/使它从文件系统的顶部开始。注意：文件系统路径，而不是网站路径（您不是通过 HTTP 访问它）。您可以使用相对路径 with include_once（不以前导开头的路径/）。
You can change it to this:
您可以将其更改为：
include_once 'headerSite.php';
That will look first in the same directory as the file that's including it (i.e. C:\xampp\htdocs\PoliticalForum\in your example.
这将首先在与包含它的文件相同的目录中查找（即C:\xampp\htdocs\PoliticalForum\在您的示例中。

include() needs a full file path, relative to the file system's root directory.
include() 需要一个完整的文件路径，相对于文件系统的根目录。
This should work:
这应该有效：
include_once("C:/xampp/htdocs/PoliticalForum/headerSite.php");

you can use:
您可以使用：
define("PATH_ROOT", dirname(__FILE__));
include_once PATH_ROOT . "/PoliticalForum/headerSite.php";

Failed to open stream error occurs because the given path is wrong such as:
无法打开流错误发生，因为给定的路径是错误的，例如：
$uploadedFile->saveAs(Yii::app()->request->baseUrl.'/images/'.$model->user_photo);
It will give an error if the images folder will not allow you to store images, be sure your folder is readable
如果图像文件夹不允许您存储图像，则会出现错误，请确保您的文件夹可读
