laravel 5.1或if语句不起作用

Question

好，

简单的IF语句，简单的代码，由于某种原因无法找到解决方案

if (substr(Auth::User()->email, -14) != "@thomasmore.be" || substr(Auth::User()->email, -22) != "@student.thomasmore.be")
    {
        echo substr(Auth::User()->email, -14);
    }

回声：

  

@ thomasmore.be

当我使用时：

if(substr(Auth::User()->email, -14) != "@thomasmore.be") 

效果很好。

我做错了什么？
