syntax error, unexpected T_IS_NOT_EQUAL in /home2/krisindi/public_html/deletead.php on line 4

    $password = $_POST["password"];

if ( $password ) != 0 )
        {
                $id = $data->select ("Classified", "AdID", array ("Password => ($password)));
                $data->delete ( "AdExtraField" , array ( "AdID" => intval ( $id["AdID"] ) ) ) ;
                $data->delete ( "Classified" , array ( "Password" => ( $password ) ) ) ;
                exec ( "chmod ../media/ 777" ) ;


                $image_file = "../media/cls_".$id["AdID"]."_520.jpg" ;
                if ( file_exists ( $image_file ) )
                        unlink ( $image_file ) ;

                for ( $i = 1 ; $i <= 5 ; $i++ )
                {
                        $image_file = "../media/cls_".$id["AdID"]."_".$i."_520.jpg" ;
                        if ( file_exists ( $image_file ) )
                                unlink ( $image_file ) ;
                }


                exec ( "chmod ../media/ 755" ) ;

                $_SESSION["str_system_message"] = "Classified deleted successfully." ;
        }
