我有一个应用程序,它为我的PHP传递一个变量(nomecardapioBD,它接收并记录在变量:nomecardapioBD),这是我想要选择所有行和列的表名.

但通过邮局收到变量无法进行预约.谁能告诉我这部分代码有什么问题？

$query = "Select * FROM :nomecardapioBD ";

  $query_params = array(
        ':nomecardapioBD' => $_POST['nomecardapioBD']
    );

//execute query
try {
    $stmt   = $db->prepare($query);
    $result = $stmt->execute($query_params);
}
catch (PDOException $ex) {
    $response["success"] = 0;
    $response["message"] = "Database Error!";
    die(json_encode($response));
}

// Finally, we can retrieve all of the found rows into an array using fetchAll 
$rows = $stmt->fetchAll();
