Need help with Abstract Function

[eldan88]

Hey guys. I am just getting into using abstract methods, and I am just trying to do a simple function to echo out the word "q64".

 

When i run the code i get the following 2 errors.

 

Use of undefined constant queens_bus - assumed 'queens_bus' in /media/sf_sandbox/abstract.php on line 17

Fatal error: Call to a member function bus_name() on a non-object in /media/sf_sandbox/abstract.php on line 18

 

Can you guys please help me and tell me whats incorrect with the code below?

<?php

abstract class Bus {

    abstract public function bus_name() ;
    

}

  class queens_bus extends Bus {
     public function bus_name() {
       echo "q64" ;
    }
  }

$new = queens_bus;
$new->bus_name();

?>

$new = new queens_bus;

$new = new queens_bus;
