$uname=$_POST["username"];

$pwd=$_POST["password"];

$link = mysql_connect('localhost', 'root', '123456')

or die('Could not connect: ' . mysql_error());

mysql_select_db('ruida') or die('Could not select database');

// 执行 SQL 查询

$query = 'SELECT * FROM user';

$result = mysql_query($query) or die('Query failed: ' . mysql_error());

while($row=mysql_fetch_array($result)){

if($uname==$row['username'] && $pwd==$row['password'])

{

//页面跳转

}

else

echo 'error!';}

// 释放结果集

mysql_free_result($result);

// 关闭连接

mysql_close($link);
