下面我们要讲到二种用户登录方法一种是利用window验证加数据库教程密码验证实现登录,后者是利用cookie记录用户信息进行登录,有需要的朋友可以试下。
function authenticate_user() {
header('WWW-Authenticate: Basic realm="Secret Stash"');
header("HTTP/1.0 401 Unauthorized");
exit;
}if (! isset($_SERVER['PHP_AUTH_USER'])) {
authenticate_user();
} else {
mysql教程_pconnect("localhost","authenticator","secret") or die("Can't connect to database server!");
mysql_select_db("java2s") or die("Can't select authentication database!");$query = "SELECT username, ps教程wd FROM user WHERE username='$_SERVER[PHP_AUTH_USER]' AND pswd=MD5('$_SERVER[PHP_AUTH_PW]')";
$result = mysql_query($query);
// If nothing was found, reprompt the user for the login www.zhutiai.com information.
if (mysql_num_rows($result) == 0) {
authenticate_user();
}
}
?>
