Does $this in PHP represent the current class or method?

Question

class DBmodel{
    private $name;
    publice function delete($name){
        $this->name = $name;
    }
}

Does $this inside represent the entire class DBmodel, or the class method delete?

Answer 1

$this represents an object, and the environment where $this is located is inside the method inside the class, so the $this object is accessed inside the class

Answer 2

Does $this in

//如果里面有构造方法：
function __construct(){
$this->name = $name;
}

represent the constructor method itself?
