Flash Builder Application, WAMP Server, PHP Service Problem

Hye there,

I am Ankit Tanna and I am a developer and a designer.
I am currently facing problems with the database connectivities of the Flash Builder form with the WAMP server.

I am using Flash Builder 4.5 along with the Zend AMF framework to connect the php services to the WAMP server database.

The thing goes like this, I am unable to use generate the sample service from the WAMP database since my Flash Buider 4.5 is crashing again and again. Hence I decided to write my own php service file for the database connectivity.

The details of the WAMP server database goes like this:

- username: root

- password: blank

- hostname: localhost

- port number: 80

- database name: rmxuserdb

- table name: users

I have built a form with a few fields which is as shown in the figure:

I am using this service code for connecting to the database:

class UserService {

    var $username = "root";

    var $password = "root";

    var $server = "localhost";

    var $port = "3306";

    var $databasename = "employees";

    var $tablename = "employees";

    var $connection;

    /**

     * The constructor initializes the connection to database. Everytime a request is

     * received by Zend AMF, an instance of the service class is created and then the

     * requested method is invoked.

     */

public function _construct() {

$this->connection = mysqli_connect(

$this->server, 

$this->username, 

$this->password,

$this->databasename,

$this->port

                              );

$this->throwExceptionOnError($this->connection);

    }

public function createUser($item) {

$stmt = mysqli_prepare($this->connection, "INSERT INTO $this->tablename (fname, lname, email, username, password, dob, address, city, state, zip, country, mobile, url) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)");        

$this->throwExceptionOnError();

mysqli_bind_param($stmt, 'isssss', $item->fname, $item->lname, $item->email, $item->username, $item->password, $item->dob, $item->address, $item->city, $item->state, $item->zip, $item->country, $item->mobile, $item->url);

$this->throwExceptionOnError();

mysqli_stmt_execute($stmt);        

$this->throwExceptionOnError);

$autoid = mysqli_stmt_insert_id($stmt);

mysqli_stmt_free_result($stmt);        

mysqli_close($this->connection);

return $autoid;

    }

?>

Upon refreshing the service I get the following error:

I am not sure where to place this services file in which folder.

Please guide me through this.

Thank you.

Ankit Tanna.
