PHP member variable assignment with connector error

Today, a problem has been encountered, assigning a value to a member variable in a class, always giving an error. is a constant connecting a string

classFileUploadControllerextendsController{private$path = BASEDIR."/Public/Upload";           //上传文件保存你路径private$allowTypearray('jpg','png','gif');          //文件限制格式

If a constant or variable is included in the original member variable, and the connection string is to be assigned a value by constructing the member variable, the constant is not visible in the class

publicfunction__construct(){$this__DIR__."/Public/Upload";    }

No construction method if only constants are included

'). addclass (' pre-numbering '). Hide (); $ (this). addclass (' has-numbering '). Parent (). append ($numbering); for (i = 1; i <= lines; i++) {$numbering. Append ($ ('

'). Text (i)); }; $numbering. FadeIn (1700); }); });

The above describes the PHP member variable assignment with the connector error, including the content of uploading files, I hope that the PHP tutorial interested in a friend helpful.
