Data Manager Programming Problems

Hi,
I'm trying to develop a class to write new threads on vbulletin.

This is my code

PHP Code:

<?php 

// ######################### REQUIRE BACK-END ############################
require_once('./global.php');


    class codeigniter_bridge{
        
        function codeigniter_bridge(){
            
            echo "Create Object <br/>";
            
            $this->threaddm =& datamanager_init('Thread', $vbulletin, ERRTYPE_ARRAY, 'threadpost'); 
            
            echo "Object Created<br/>";
        }
        
        
        function postThread(){
            echo "Call Prova<br/>";
            $class_methods = get_class_methods($this->threaddm);

            foreach ($class_methods as $method_name) {
                echo "$method_name\n";
            }
            
        }
    }

    $vb = new codeigniter_bridge();
    $vb->postThread();
?>

and this is what appens:

Where I do wrong?

Thank you!
