刚把网站迁移过来,看下了根目录的index.php 显示 数据库连接文件的代码
//数据库类
require_once('class/dbconfig.php');
require_once('class/class_user.php');
require_once('class/class_public.php');
require_once('class/class_shop.php');

打开class/dbconfig.php 这个文件 代码是

-->class dbconfig {
        
        //连接数据库
        function con()
        {
            $con = mysql_connect('127.0.0.1', 'root', '123456');
            
            mysql_select_db("database_591", $con);
            
            return $con;
            
        }
        
        //执行SQL
        function getRs($sql,$con)
        {
            mysql_query('set names utf8');
            
            return mysql_query($sql, $con);
            
        }
        
        //执行SQL,不返回值
        function deff_getRs($sql,$con) 
        {
            mysql_unbuffered_query('set names utf8');
            
            return mysql_unbuffered_query($sql, $con);
            
        }
        
        //关闭数据集
        function clearRS($rs) {
            mysql_free_result($rs);
            
        }
        
        //关闭数据库
        function clearDB($con) {
            mysql_close($con);
            
        }
        
        //数据集条数
        function rsRows($rs) {
            return mysql_num_rows($rs);
            
        }
        
        //数据集指针
        function rsSeek($rs, $n = 0 ) {
            return mysql_data_seek($rs, $n);
            
        }
        
    }
    
    $db = new dbconfig;
?>
Copy after login


只把123456 改成了 自己的数据库密码

但还是连接不上数据库 网站打不开 其他相关的数据库文件 也一样改过 还是不行 请问是什么问题呢 PHP新手 谢谢指教

目录名是是 _519
那么数据库名就是 _519

mysql_select_db("_591", $con);
