我想连接我的：在线MySQL数据库，但我得到这个错误。有人能帮我吗？

Question

我要让连接到我的在线数据库，但后来我得到这个错误：

Warning: mysqli :: mysqli(): (HY000/2002): A connection attempt failed because the " Related party Incorrectly If the answer after a certain time , of the costs Connection failed because " the Confederate host has not responded . C: \ wamp \ www \ array Add in db \ 222.php on line 8

这是我的代码：

?php 

$servername = "db.tapdeleest.nl"; $username = "***"; $password = "***"; $dbname = "***"; 
// Create connection 
$conn = new mysqli($servername, $username, $password, $dbname); 
// Check connection 
if ($conn->connect_error) { 
die("Connection failed: " . $conn->connect_error); 
} 
else 
{ 
echo "nice"; 
} 

?> 

感谢您的帮助！

使用新的mysqli（），您不会在连接中添加数据库名称。

您使用mysqli_select_db（$康恩，$ DBNAME）

<?php 

$servername = "db.tapdeleest.nl"; $username = "***"; $password = "***"; $dbname = "***"; 
// Create connection 
$conn = new mysqli($servername, $username, $password); 
// Check connection 
if ($conn->connect_error) { 
    die("Connection failed: " . $conn->connect_error); 
} 
else 
{ 
    echo "nice"; 
    mysqli_select_db($conn, $dbname); 
} 

?> 

只是建议：给PDO一试，我觉得PDO更容易。 http://www.w3schools.com/php/php_mysql_connect.asp
