Any help would be great as i am completely lost.
推荐答案
好吧，您只能在类中使用 $this.在类之外，$this 不应该存在.它基本上引用了您在其中工作的当前类对象.要使其正常工作，您需要将一个变量定义为一个新类，然后通过该变量引用所有内容，例如:
Well you can only use $this inside of a class. Outside of a class, $this shouldn't exist. It basically references the current class object that you're working inside of. To get this working properly, you need to define a variable as a new class and then reference everything through that variable, such as:
$myvar = new MyClass();
$h1 = $myvar->params->get("logo");
如果那是你正在做的事情.
If that's the kind of thing you're doing.
