Understanding and examples of $this in PHP

When we write php scripts, we often use $this, so how do we understand $this?

Next, I will demonstrate the use of $this:

First of all, we usually create a class when writing a script, so we first create a class User

class User { public $name; }

Next, we write another method getName(). The function of this method is to output the attribute $name

class User { public $name; public function getName() { echo $this->name; } } //使用 $user1 = new User(); $user1->name = 'liming'; $user1->getName();//会输出'liming' $user2 = new User(); $user2->name = 'zhagsan'; $user2->getName();//输出'zhangsan'

How to understand?

The above example creates two objects. When $user1->getName, at this time, $this represents $user1.

The above is my understanding, I hope it will be helpful to everyone. Thanks!
