问题描述
b $ b
我知道这是非常基本的。我在YouTube上看到关于CakePHP和PHP的教程,他们都在使用$ this,但没有人实际上说它是什么或用于什么。我认为它是一个变量,但它包含什么,为什么所有的函数必须从它运行?是当前类吗?我阅读了,$ this与自己不同,因此我不确定
I know this is extremely basic. I am watching tutorials on YouTube about CakePHP and PHP and all of them keep using "$this", but none of them actually say what it is or what it is used for. I think it is a variable, but what does it contain, and why do all of the functions have to be run from it? Is it the current class? I read here that "$this" is different from self though, so I am not sure if this is the case.
推荐答案
如果在类中使用, $ this
指的是它所在的对象。
if used in a class, $this
refers to the object that it's in.
