请参阅http://ericlippert.com/2014/03/05/how-to-debug-small-programs/ – Samuel

通过Google搜索“如何解决注意：未定义的PHP索引”来修复您的未定义索引。然后，我建议为'注意：一个会话已经开始'为第二种类型的错误做一个谷歌。我会留下解决方案，以解决第三种错误达到您的想象，但其解决方案与第一种和第二种错误的解决方案类似。一旦Google完成，写/改变少量的代码，瞧。错误修复。 – MLeFevre

添加一个简单的isset检查是否存在会话中的authData值会解决此问题。

if(isset($_SESSION['authData'])){ 

     $this->authData = $_SESSION['authData']; 
}

$ _ SERVER [ 'HTTP_REFERER']不会，如果你直接打开页面设置。所以最好是检查它的价值在使用前：

if(isset($_SERVER['HTTP_REFERER']) 
    ...do something here

另外，请确保您设置$_SESSION['authData']使用它

最后，MongoClient应该使用它之前定义之前。我没有看到它的任何地方。
