I am getting the above warning when I try to run this code:

$mysqli=new mysqli("localhost", "***", "***","***") or die(mysql_error());


              function checklogin($username, $password){
                global $mysqli;


                $result = $mysqli->prepare("SELECT * FROM users WHERE username = ?");
                $result->bind_param("s", $username);
                $result->execute();

            if($result != false){

                $dbArray=mysql_fetch_array($result);
