You don't use $_SERVER['DOCUMENT_ROOT']for this, you want to use APPPATHor BASEPATHinstead, or just type the full path to the file. require_onceshould be passed a local file, not a URL.
你不使用$_SERVER['DOCUMENT_ROOT']这个，你想使用APPPATHorBASEPATH代替，或者只是输入文件的完整路径。 require_once应该传递一个本地文件，而不是一个 URL。

You should be using the path to the file and not the URL. Best (and certainly CI friendly) way would be to use BASEPATHor APPPATHconstants.
您应该使用文件的路径而不是 URL。最好的（当然也是 CI 友好的）方法是使用BASEPATH或APPPATH常量。
