你能知道固有的孩子名字吗？

I have a clase Base in PHP for inherit it to many children classes, managing errors into Base class, I try to print in screen where the error occurs, Can I get the child class name to show in the error during the Exception in Base parent Class?

Yes you can using get_class()

class Base{
    public function printBase(){
        echo get_class($this);
    }
}

class Ext extends Base{}

$ext = new Ext();
$ext->printBase(); //Output: Ext

The function get_called_class() resolve my problem, this throws the name of the class who is calling. http://php.net/manual/es/function.get-called-class.php
