警告:mysqli_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: No such host is known [英] Warning: mysqli_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: No such host is known

问题描述

我刚刚下载了 wamp 服务器.我想用 PHP 建立到 MySQL 数据库的连接，我使用的是 root 用户、localhost 和我的数据库的名称.我的代码似乎是正确的，但是当我在 wamp 上运行它时，出现以下错误:警告:mysqli_connect():php_network_getaddresses:getaddrinfo 失败:不知道这样的主机.在 C:\wamp\www\cone.php 第 8 行和警告:mysqli_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: No such host is known.

I have just downloaded the wamp server. I want to establish a connection to MySQL database with PHP and I'm using the root user, localhost and the name of my database. My code seems to be correct but when I run it on wamp, I get the following error: Warning: mysqli_connect(): php_network_getaddresses: getaddrinfo failed: No such host is known. in C:\wamp\www\cone.php on line 8 and Warning: mysqli_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: No such host is known.

此外，还显示了我尚未连接到数据库(来自我的 if 语句)的错误消息.

Also, the error message that I haven't been connected to the database(from my if statement) is displayed.

这是否意味着我必须在服务器上做一些额外的配置?

Does this mean that I have to do some extra configuration on the server?

这是我的代码:

$dbcon = mysqli_connect('root','', 'localhost', 'people');

`if(!$dbcon)` 
`{`
    `die('error connecting to database');`
`}`
`echo "success";`

?>

提前致谢

推荐答案

mysqli_connect('root','', 'localhost', 'people');

您将 root 作为主机名传入.

You are passing root in as hostname.

试试这个

mysqli_connect('localhost','root', '', 'people');

这将使用用户名 root 密码 "" 和默认数据库人员连接到本地主机.

this will connect to localhost with username root passwoord "" and default database people.

最好用 127.0.0.1 更改 localhost

maybe better to change localhost with 127.0.0.1
