【问题描述】：

我的网页上出现了两个错误。而且我不太习惯搞数据库，mysql，所以我需要你帮助我！

警告：mysqli_connect(): (28000/1045): Access denied for user 'u467224226_yjygu'@'10.1.2.19' (using password: YES) in /home/u467224226/public_html/galeria/api.php on line 8

警告：mysqli_error() 期望参数 1 为 mysqli，布尔值在 /home/u467224226/public_html/galeria/api.php 第 8 行给出

这是代码。

<?php // connect to the database $user_name = ""; $password = ""; $database = ""; $host_name = "localhost";

$con = mysqli_connect($host_name ,$user_name ,$password,$database) or die("Error " .       mysqli_error($con)); //check connection

echo "Connection opened";

mysql_close($con); ?>

<?php   require_once('include/config.inc.php');     header("Content-type: application/x-javascript");
    
    
            $connect = mysql_connect($CONFIG['dbserver'],$CONFIG['dbuser'],$CONFIG['dbpass'])       or die('Erro ao conectar ao servidor');     $connect_db = mysql_select_db($CONFIG['dbname'], $connect)      or die ('Erro ao conectar ao banco de dados');

select Host, User from mysql.user;

查看为您的用户列出的内容。

如果它丢失了，你可以运行：

CREATE USER 'u467224226_yjygu'@'%%' IDENTIFIED BY 'PASSWORD';
