How does PHP get the current class name, the problem in the inheritance?

The wood has the title to say so simple!!

The problem is:

Class A in PHP Inherits Class B, and how to get classes name of Class B in Class A

The actual conditions of use are:

Class B is a base class, multiple classes a,c,d ..... Need to inherit class B. I want to write some logs in class B to record the operation of Class A.

The actual conditions of use are:

My way is relatively simple, in the class B to define a property, B in the constructor of the __class__ assignment to this property, the subclass call this property to know the class name of B.
Code:
Class b{

    protected $name = '';    public function __construct(){        $this->name = __CLASS__;    }}class A extends B{    public function _show(){        echo $this->name;    }}$temp = new A();$temp->_show();

Defining a function is just fine.
Base classes and subclasses can be called from one another.

You write a function in Class B (Word Class):

private function getChildName(){    return __CLASS__;}

You can call it in Class A (base class):

$this->getChildName();

Multiple inheritance to get the parent class name in the subclass 1. Use reflection 2. Use callbacks (including child-parent calls) 3. Define the Self-class method in the parent class.

The landlord raised the question seems to be:

Because A,c,d are inherited B, the functions in B need to be "A, or c" "?

class Base {    public function log() {        // 目标类，输出：A、C        echo static::class;        //echo get_called_class();        //echo get_class($this);                        // 基类，输出：Base        //echo __CLASS__;         //echo self::class;            }}class A extends Base {}class C extends Base {}echo (new A)->log();  // 输出： Aecho (new C)->log();  // 输出： C

If your needs are in a, know who inherits, this can be used to reflect the

// 类外获得$a = new A();echo get_parent_class($a);//类中获得class C extends Base {    public function log1() {       echo get_parent_class($this);    }}// 反射，取出所有extends的父级// 如上，在C类中，$a换成$this即可$class = new ReflectionClass($a);$parents = [];while ($class = $class->getParentClass()) {  // 查询 implements 用 getInterfaces       $parents[] = $class->getName();}print_r($parents);
