Why do I get that Error when I use include_once:

   include_once("/PoliticalForum/headerSite.php");

回答1:

It's because you have included a leading / in your file path. The / makes it start at the top of your filesystem. Note: filesystem path, not Web site path (you're not accessing it over HTTP). You can use a relative path with include_once (one that doesn't start with a leading /).

You can change it to this:

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.

回答2:

include() needs a full file path, relative to the file system's root directory.

This should work:

 include_once("C:/xampp/htdocs/PoliticalForum/headerSite.php");

回答3:

you can use:

define("PATH_ROOT", dirname(__FILE__));
include_once PATH_ROOT . "/PoliticalForum/headerSite.php";

回答4:

Failed to open stream error occurs because the given path is wrong such as:

$uploadedFile->saveAs(Yii::app()->request->baseUrl.'/images/'.$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
