Question

我的mysql为什么与php连接老是有问题？

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: YES) in E:\zct\mylove\test\test.php on line 2
数据连接失败！
源代码：
<?php
if(!mysql_connect('localhost','root',' '))（密码为空格）
die(数据连接失败！);
mysql_select_db('test');
?>

Answer 1

$link = @mysql_connect('localhost','root','root') or die('数据库连接失败!');
mysql_select_db(DBNAME,$link);
mysql_query('set names utf8');
$sql = "select * from tree order by concat(path,id)";
