PHP100中，制作自己的PHP.MYSQL类中：Access denied for user ''@'localhost' (using password:

具体代码如下：

class su{
private $host;
private $root;
private $pass;
private $name;
private $table;

function __construct($host,$root,$pass,$table){
$this->host=$host;
$this->root=$root;
$this->pass=$pass;
$this->table=$table;

}
function connect(){
$con=mysql_connect($this->host,$this->root,$this->pass) or die(mysql_error());
$sel=mysql_select_db($this->table,$con)or die(mysql_error());
$ch=mysql_query("set names 'gbk'");
}
function query($v){
return mysql_query($v) or die(mysql_error());
}
function insert($table,$name,$value){
$this->query("insert into $table ($name) value ($value)");
}
}
$p=new su('localhost','root','448824','susheguangli');
$p->insert("susheguangli","工号,姓名,性别,入职时间,入住宿舍,床位,户口,工资","6498,'高榆','男',new(),new(),3,'止州花东',2300");
?>

你的数据库没有密码，但是你配置了密码

access denied for user ''@'localhost' to database 我在suse linux 10.2下用自带光盘用yast2安装mysql 5.0, 装好后在终端输入mysql, mysql 成功启动，退出，再输入 mysqladmin -u root password xxxxx， 出现错误： mysqladmin: connect to server at 'localhost' failed error: 'access denied for user 'root'@'localhost' (using password: no)' 如先输入mysql,成功启动后输入use mysql,出现如下错误：access denied for user ''@'localhost' to database 'mysql' 还有，输mysql可以，输mysql -u root就出错了： access denied for user 'root'@'localhost' (using password: no).
