php - mysql 数据库连接

Question

我正在尝试连接到我的数据库以从 sql workbench 检索表，但是当我这样做时，它会出现以下错误消息

could not connect to MySQL Unknown MySQL server host "Guada"

php脚本如下:

<?php

//Using details to establish database connection
DEFINE ('DB_USER', 'i7421760');
DEFINE ('DB PASSWORD', '*********');
DEFINE ('DB_HOST', 'guada');
DEFINE ('DB_NAME', 'i7421760');




$dbc = @mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME)
OR die('could not connect to MySQL ' .
        mysqli_connect_error());
/*
If the connection couldn't be established it 
will print a display message and the error report
*/
?>

如果只是主机名错误的话，到哪里去找呢？我想要检索的表位于 sql workbench 上。

任何帮助表示赞赏 提前致谢

更新您的代码:

//Using details to establish database connection
DEFINE ('DB_USER', 'i7421760');
DEFINE ('DB PASSWORD', '*********');
DEFINE ('DB_HOST', 'localhost');
DEFINE ('DB_NAME', 'i7421760');




$dbc = @mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME)
OR die('could not connect to MySQL ' .
        mysqli_connect_error());
/*
If the connection couldn't be established it 
will print a display message and the error report
