<?php

class dad {
    function 
dad()
    {
    
// implements some logic
    
}
}

class 
child extends dad {
    function 
child()
    {
        echo 
"I'm " get_parent_class($this) , "'s son\n";
    }
}

class 
child2 extends dad {
    function 
child2()
    {
        echo 
"I'm " get_parent_class('child2') , "'s son too\n";
    }
}

$foo = new child();
$bar = new child2();

?>
