    @mysql_select_db($database) or die("Unable to find database");

    $name = isset($_GET["name"]) ? $_GET["name"] : '';

在几位帮助者评论之后,这是正确的解决方案,并且它有效.感谢所有回复的帮助者.

$dbhost = "fdb7.biz.nf";
$database = "2065616_knurum";
$username = "2065616_knurum";
$dbpass = "XXXXXXXX";

$link = mysqli_connect($dbhost,$database);

if (!$link) {
    echo "Error: Unable to connect to MySQL." . PHP_EOL;
    echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
    echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
    exit;
}


$name = isset($_GET["name"]) ? $_GET["name"] : '';

$message = isset($_GET["message"]) ? $_GET["message"] : '';

$query = "INSERT INTO test VALUES ('','$message')";

mysqli_query($link,$query) or die (mysqli_error("error"));


echo "Success: A proper connection to MySQL was made! The my_db database is great." . PHP_EOL;
echo "Host information: " . mysqli_get_host_info($link) . PHP_EOL;
mysqli_close($link);
?>
