List all classes inherited from

Is it possible to list all classes that have extended from class:-

So for example, I want to create a class called certificate, but there are several types of certificate some will override function from certificate some wont, so Ive set it up like:-
<?php
	class certificate {
		public function getDesciption() {
			return 'No description stored';
		}
	}













	class foo extends certicate {
		public function getDesciption() {
			return 'This is a Foo certificate';
	    	}
	}


	class bar extends certicate {
		public function getDesciption() {
			return 'This is a bar certificate';
		}
	}
?>

Open in new window


However if I want to list all the objects created from 'certificate' and call 'getDescription' from each, is there a method in PHP to list all objects created, and see what it extends from?

Thank you in advance

See if this makes some sense.

<?php // demo/temp_tonelm54.php
ini_set('display_errors', TRUE);
error_reporting(E_ALL);

class Certificate
{
    public function getDescription()
    {
        echo PHP_EOL . 'This is a ' .  get_class($this) . ' certificate';
    }

    public function whoAmI()
    {
        echo PHP_EOL . 'I am an Object Instance of ' .  get_class($this);
    }
}

class Foo extends certificate
{
    public function getDescription()
    {
        echo PHP_EOL . 'This is a ' .  get_class($this) . ' certificate';
    }
}

class Bar extends certificate
{
    public function getDescription()
    {
        echo PHP_EOL . 'This is a ' .  get_class($this) . ' certificate';
    }
}

echo '<pre>';
$c = new Certificate;
$f = new Foo;
$b = new Bar;

$c->getdescription();
$f->getdescription();
$b->getdescription();

$c->whoami();
$f->whoami();
$b->whoami();

Maybe something like this?
http://php.net/manual/en/function.get-called-class.php

The question is kind of counterintuitive because your own PHP code will create the objects, so looking for a PHP function to tell you what objects you created doesn't make sense to me.  It would make more sense to keep an internal record of the classes used to instantiate the objects.  An array of objects is a very useful programming construct!
