Warning: mysqli_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: No such host is known
提问by Stelios Voskos
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.
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：没有已知这样的主机。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。
Also, the error message that I haven't been connected to the database(from my if statement) is displayed.
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。
Does this mean that I have to do some extra configuration on the server?
这是否意味着我必须在服务器上做一些额外的配置？
Here is my code:
这是我的代码：
<?php
<?php
$dbcon = mysqli_connect('root','', 'localhost', 'people');
$dbcon = mysqli_connect('root','', 'localhost', 'people');
`if(!$dbcon)`
`{`
`die('error connecting to database');`
`}`
`echo "success";`
?>
?>
Thank you in advance
先感谢您

mysqli_connect('root','', 'localhost', 'people');
You are passing root in as hostname.
您将 root 作为主机名传入。
try this
尝试这个
mysqli_connect('localhost','root', '', 'people');
this will connect to localhost with username root passwoord "" and default database 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。
maybe better to change localhost with 127.0.0.1
用 127.0.0.1 更改 localhost 可能更好
