代码：

    // Check connection
    if (mysqli_connect_error()) {
        die("Database connection failed: " . mysqli_connect_error());
    }
    $to = "admin@gmail.com";

    $message = "G'Day!]

    Your personal account for the Project Web Site
    has been created! To log in, proceed to the
    following address:

    http://www.example.com/

    Your personal login ID and password are as follows:


    You aren't stuck with this password! You can change it at any time after you have logged in.

    If you have any problems, feel free to contact me at <you@example.com>.

    -Your Name
    Your Site Webmaster
    ";



    $sql = mail($to,"Your Password for Your Website",$message,"From:Your Name <you@example.com>");

    if ($conn->query($sql) === TRUE) {
        echo "Email has successfully been sent!";
    } else {
        echo "Error: " . $sql . "<br/>" . $conn->error;
    }



    $conn->close();

?>

// css

if($row) // Ime nije registrovano kod dole
{
    echo '

        <div class="transbox" position = "center">
