语法错误，意外'$ alert'（T_VARIABLE）

Question

hmm i d'ont understand why I have this error:

Parse error: syntax error, unexpected '$alert' (T_VARIABLE) in C:\wamp\www\envMailAuto\controler.php on line 19

my controler:

include 'modele.php';

$email=$_REQUEST["email2"];
if(isset($_REQUEST["check"])) echo $email;
else echo "omged";
$idarticle = 3555;

$DB_host     = "localhost";
   $DB_select   = "envmail";
   $DB_login    = "root";
   $DB_pass     = '';

$connection=mysql_connect($DB_host,$DB_login,$DB_pass); 

$db=mysql_select_db($DB_select, $conn);


alertarticleDAO $alert = new __alertarticle($connection);

my model:

Class alertarticleDAO {

var $connection;

public function __alertarticle($mysqlconnection){
$this->connection = $mysqlconnection;
}

public function insert($Idarticle,$email){
$query=" INSERT INTO envmail ( mail_env , id_article , actif )
VALUES ( $Idarticle , $email , 1)";

mysql_query($query,$this->connection);

}


}

In PHP you don't need to specify the type when you initialize an object. Change this line:

alertarticleDAO $alert = new __alertarticle($connection);

into this:

$alert = new alertarticle($connection);

and the constructor definition is also wrong, change this:

public function __alertarticle($mysqlconnection){

into this:

function __construct($mysqlconnection){
