Hello.

I have changed some of my old queries to the Mysqli framework to improve performance. Everything works fine on localhost but when i upload it to the webserver it outputs nothing. After connecting I check for errors and there are none. I also checked the php modules installed and mysqli is enabled.

I am certain that it creates a connection to the database as no errors are displayed. (when i changed the database name string it gave the error)

There is no output from the query on the webserver, which looks like this:

$mysqli = new mysqli("server", "user", "password");

if (mysqli_connect_errno()) {
   printf("Can't connect Errorcode: %s\n", mysqli_connect_error());
   exit;
}

// Query used  
$query = "SELECT name FROM users WHERE id = ?";

if ($stmt = $mysqli->prepare("$query")) 
{

    // Specify parameters to replace '?'
    $stmt->bind_param("d", $id);  

    $stmt->execute();

    // bind variables to prepared statement 
    $stmt->bind_result($_userName);

    while ($stmt->fetch()) 
    {
          echo $_userName;
    }

$stmt->close(); } }

//close connection $mysqli->close();

As I said this code works perfectly on my localserver just not online. Checked the error logs and there is nothing so everything points to a good connection. All the tables exists as well etc. Anyone any ideas because this one has me stuck! Also, if i get this working, will all my other queries still work? Or will i need to make them use the mysqli framework as well? Thanks in advance.
