PHP and Flash Builder

[Placido]

hi all,

I will explain my problem, I hope you can help.

I am making an application in flash builder 4. This software uses the language php to connect to the database (I'm using the wampserver).

When I try to do an insertion in the database it returns me these errors:

php-error file:
PHP Fatal error: Call to a member function toString() on a non-object in C:\wamp\www\Maxiclinic\bin-debug\services\UtenteService.php on line 124

apache_error file;
[error] [client 127.0.0.1] File does not exist: C:/wamp/www/favicon.ico

and my php code:

class UtenteService {

    var $username = "root";
    var $password = "";
    var $server = "localhost";
    var $port = "3306";
    var $databasename = "clinic_db";
    var $tablename = "utente";

    var $connection;

    /** 3306
     * 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 createUtente($item) {

        $stmt = mysqli_prepare($this->connection, "INSERT INTO $this->tablename (Nome, Morada, CodigoPostal, SubCodigoPostal, Localidade, Profissao, Alerta, Telefone, Telemovel, Email, DataNascimento, EstadoCivil, SistemaSaude, NumeroUtente, BI, NumeroFiscal, MedicoFamilia, Foto, Habilitacoes) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)");
        $this->throwExceptionOnError();

        //mysqli_stmt_bind_param($stmt, 'ssiisisiissiiiiissi', $item->Nome, $item->Morada, $item->CodigoPostal, $item->SubCodigoPostal, $item->Localidade, $item->Profissao, $item->Alerta, $item->Telefone, $item->Telemovel, $item->Email, $item->DataNascimento->toString('YYYY-MM-dd HH:mm:ss'), $item->EstadoCivil, $item->SistemaSaude, $item->NumeroUtente, $item->BI, $item->NumeroFiscal, $item->MedicoFamilia, $item->Foto, $item->Habilitacoes);
        $stmt->bind_param('ssiisisiissiiiiissi', $item->Nome, $item->Morada, $item->CodigoPostal, $item->SubCodigoPostal, $item->Localidade, $item->Profissao, $item->Alerta, $item->Telefone, $item->Telemovel, $item->Email, $item->DataNascimento->toString('YYYY-MM-dd HH:mm:ss'), $item->EstadoCivil, $item->SistemaSaude, $item->NumeroUtente, $item->BI, $item->NumeroFiscal, $item->MedicoFamilia, $item->Foto, $item->Habilitacoes);
        $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;
    } 

Anyone know how I can fix?
thanks for the all help you can give
