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!
