复制代码 代码如下:
<?php
$uname=$_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);
?>
