请教大侠一个小问题，php的，解决不了了，急

Question

还要指明目录名
header("location:http://(localhost)/(dirname)/index.php");

Answer 1

其实用JS
<script>...
location="(dirname)/index.php";
</script>

Answer 2

我觉得直接 includes(index.php) , 比较好。 不需要再与客户端交互，直接请求。

Answer 3

header("Location: http://" . $_SERVER['HTTP_HOST']
                      . dirname($_SERVER['PHP_SELF'])
                      . "/index.php");

Answer 4

$db=mysql_connect("localhost","admin");还差数据库服务器密码参数吧
