What is the purpose of the __CLASS__ keyword in PHP?

The __CLASS__ keyword in PHP is used to refer to the current class name within the class definition. It is helpful when you need to dynamically reference the class name without hardcoding it. This can be useful for creating reusable code or for situations where the class name may change. Example: 

class MyClass {
    public function getClassName() {
        return __CLASS__;
    }
}

$obj = new MyClass();
echo $obj->getClassName(); // Output: MyClass
