$这是什么意思在类定义？ [英] what does $this mean within a class definition?

问题描述

当我继续尝试改善自己作为一个初级PHP开发人员，我已经开始尝试打破其他人的工作。

As I continue to try and improve myself as a junior PHP developer, I have started to try break down other peoples work. I find it helps me understand, as well as giving me ideas.

我在PHP类中没有得到两个东西，这意味着什么，这意味着什么，什么数组

Two things I do not get, in a PHP class, what $this means, and what array($this,'some_function') means when I would expect a function name in it's place.

非常感谢

推荐答案

请参阅 PHP课程手册和对象。 $ this 是指对象实例。另请参阅以下问题：

Please see the PHP Manual on Classes and Objects. $this refers to the object instance. Also see these questions:

• PHP中的变量$ this是什么意思？


• $ this的意义

• What does the variable $this mean in PHP?
• What is the meaning of $this

array（$ this，'some_function'）请参阅 PHP手册回调。在接受回调的方法和函数中，例如 call_user_func ，意味着调用 some_function > $ this 。请参阅

For array($this,'some_function') see the PHP manual on callbacks. In methods and functions that do accept callbacks, like call_user_func, it means call the method some_function on $this. See
