php 警告：mysqli_connect()：php_network_getaddresses：getaddrinfo 失败：不知道这样的主机。但我显然必须在那里主持

Warning: mysqli_connect(): php_network_getaddresses: getaddrinfo failed: No such host is known. Yet I clearly have to host there

I have a site written in PHP that I'm creating. But I'm having this issue when I connect it to the database. When I load the page, I get the top:

我有一个我正在创建的用 PHP 编写的网站。但是当我将它连接到数据库时，我遇到了这个问题。当我加载页面时，我得到了顶部：

Warning: mysqli_connect(): php_network_getaddresses: getaddrinfo failed:     No such host is known. in C:\Program Files\Apache Software   Foundation\Apache2.2\htdocs\socialtest\inc\connect.inc.php on line 7

Warning: mysqli_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: No such host is known. in C:\Program Files\Apache   Software Foundation\Apache2.2\htdocs\socialtest\inc\connect.inc.php on line 7

This is connect.inc.php. The file which establishes the connect to the MySQL database:

这是connect.inc.php。建立与 MySQL 数据库的连接的文件：

$dbc = mysqli_connect('USER','PASSWORD','SERVER','DATABASE');
#OR die('Captian, we have failed' .
#     mysqli_connect_error());
?>

The server name is 'localhost' and I never had a problem with it until recently.

服务器名称是“localhost”，直到最近我才遇到问题。

Please let me know how I can solve this issue as I've tried everything I can think of and I'm out of options.

请让我知道如何解决这个问题，因为我已经尝试了所有我能想到的方法，但我别无选择。

I'm using Apache2.2, PHP .5.6.9 and MySQL56 on Windows Vista.

我在 Windows Vista 上使用 Apache2.2、PHP .5.6.9 和 MySQL56。

Thanks!

谢谢！

As "mario" said, your mysqli_connect syntax is wrong.

正如“ mario”所说，您的 mysqli_connect 语法是错误的。

The right syntax is for example :

正确的语法是例如：

mysqli_connect('localhost', 'my_user', 'my_password', 'my_db');
