PHP: Is it possible to retrieve the class name of a child class?

class Bob extends Person
{
    //do some stuff
}

class Person
{
    public function __construct()
    {
        //get the class name of the class that is extending this one
        //should be Bob
    }
}

How can I get the class name of Bob from inside the constructor of the Person class?

<?php

class Bob extends Person
{

    public function __construct()
    {
        parent::__construct();
    }

    public function whoAmI()
    {
        echo "Hi! I'm ".__CLASS__.", and my parent is named " , get_parent_class($this) , ".\n";
    }
}

class Person
{
    public function __construct()
    {
        echo "Hello. My name is ".__CLASS__.", and I have a child named " , get_class($this) , ".\n";
    }
}

// Hello. My name is Person, and I have a child named Bob.
$b = new Bob;
// Hi! I'm Bob, and my parent is named Person.
$b->whoAmI();

class Person
{
  public function __construct()
  {
    echo get_class($this);
  }
}

class Bob extends Person
{
  //do some stuff
}

$b = new Bob;

prints Bob as explained in "Example #2 Using get_class() in superclass" at http://docs.php.net/get_class

Use get_class($this).

It works for sub-class, sub-sub-class, the parent class, everything. Just try it! ;)
