I am trying this piece of code for hours. I am not able to figure out what my error is. 

```
$conn = mysqli_connect('localhost', 'user', 'pass', 'mydb')
            or die( "Unable to connect");

$check = mysqli_query($conn, "select * from Users where Fuid='$fbid'",
            MYSQLI_STORE_RESULT);

$rows = mysqli_num_rows($check);

if (empty($rows)) { // if new user . Insert a new record        
    $query = "INSERT INTO Users (Fuid,Funame,Ffname,Femail)
            VALUES ('$fbid','$funame','$ffname','$femail')";

    mysqli_query($conn, $query);    
}

```

There might be a very small error, but I am just fried up.
