get child class name without passing value through the argument

This question is difficult to ask, as it seems to answer.

I have a method declared in abstract class parent{}, that gets echoed in child class foo{}

This method requires the current current class name i.e. foo to work, So how do I get this name without passing it through the argumet?

EXAMPLE

abstract class parent{
  public function init(){
     echo "I am running from class ...."; 
  // I want this to say, that is it running from any class that is extending it. 
  } 
}

This is the child class, and is only supposed to hold one username;

class foo extends parent{
   echo $this->init(); 
 // I could pass the class name through the argument, but I am looking for other alternatives  
}

 echo "I am running from class " . get_class($this);

__CLASS__ is the declaring class (the class you're using it in) and get_class will get the concrete class of the provided object. So get_class($this) will return the same value as __CLASS__ or one of its child classes.

@sroes has the answer, but your code example could be something like:

abstract class parentclass{
  public function init(){
     echo "I am running from class ...."; 
        echo __CLASS__;    

        echo ' But I am ' . get_class($this);         
  } 
}

class foo extends parentclass{
}

$f = new foo();
$f->init();

Shows diff between const CLASS and get_class()
