Login php/mysql script

Hi..I use this resource www.garagegames.com/index.php?sec=mg&mod=resource&page=view&qid=13468
And i would modify "tgeLoginDlg.gui" and i need help
I try this simply (very very very simply =P) code and function...

$pref::Player::Name = "";
$pref::Player::Password = "";

function GuiLoginDlg::onWake(%this)
{
   loginId.setCursorPos(0);
}

function requestAuth()
{
	echo("User = " @ $pref::Player::Name);
	echo("Password = " @ $pref::Player::Password);

	if($pref::Player::Password $= "entra")
	{
		showMainMenuBttnControls(true);
		Canvas.popDialog(GuiLoginDlg);
	}
	else
		Canvas.pushDialog(GuiLoginDlg);
}

Now i would use a my MySql DB and my .php login on my site

- This is my DB
[code]
CREATE TABLE utenti (
userid int(25) NOT NULL auto_increment,
nome varchar(255) NOT NULL default '',
cognome varchar(255) NOT NULL default '',
email varchar(255) NOT NULL default '',
username varchar(255) NOT NULL default '',
password varchar(255) NOT NULL default '',
password_decriptata varchar(255) NOT NULL default '',
livello_utenti enum('0','1','2','3') NOT NULL default '0',
data_registrazione datetime NOT NULL default '0000-00-00 00:00:00',
ultimo_login datetime NOT NULL default '0000-00-00 00:00:00',
attivazione enum('0','1') NOT NULL default '0',
PRIMARY KEY (userid)
) TYPE=MyISAM COMMENT='Informazioni Utenti';
[code]
And i would use a "userid" and "password_decriptata" in "tgeLoginDlg.gui"
