The workings membership.php
<?php
require 'Mysql.php';
class Membership {
function validate_user($un, $pwd) {
$mysql = New Mysql();
$ensure_credentials = $mysql->verify_Username_and_Pass($un, md5($pwd));
if($ensure_credentials) {
$_SESSION['status'] = 'authorized';
header("location: index.php");
} else return "Please enter a correct username and password";
}
function log_User_Out() {
if(isset($_SESSION['status'])) {
unset($_SESSION['status']);
if(isset($_COOKIE[session_name()]))
setcookie(session_name(), '', time() - 1000);
session_destroy();
}
}
function confirm_Member() {
session_start();
if($_SESSION['status'] !='authorized') header("location: login.php");
}
}
Mysql.php
This is what is connecting to the data base.
require_once 'includes/constants.php';
class Mysql {
private $conn;
function __construct() {
$this->conn = new mysqli(DB_SERVER, DB_USER, DB_PASSWORD, DB_NAME) or
die('There was a problem connecting to the database.');
}
function verify_Username_and_Pass($un, $pwd) {
$query = "SELECT *
FROM users
WHERE username = ? AND password = ?
LIMIT 1";
if($stmt = $this->conn->prepare($query)) {
$stmt->bind_param('ss', $un, $pwd);
$stmt->execute();
if($stmt->fetch()) {
$stmt->close();
return true;
}
}
}
}

In your index.php write the following code:
<div id="top-register">
<?
echo "Hello" .$_SESSION['username'];
?>

创建一个会话变量，该变量将保存从查询中获取的用户名，然后在页面中回显该会话变量。

I think, you missed the echo before. Change
<?
$_SESSION['username']
?>
to
<?
echo $_SESSION['username']
?>

In class Membership change this...
if($ensure_credentials) {
$_SESSION['status'] = 'authorized';
header("location: index.php");
} else return "Please enter a correct username and password";
To this...
if($ensure_credentials) {
$_SESSION['status'] = 'authorized';
$_SESSION['username'] = $un;
header("location: index.php");
} else return "Please enter a correct username and password";

I used the same nettuts tutorial for my user login page. This is what works for me to show logged in user on index.php page.
INSERT IN BODY OF INDEX.PHP PAGE:
<?php
echo "Welcome ", $_SESSION['username'];
?>

我认为您错过了在index.php页面上开始会话的时间，因此请在页面开头输入此行
session_start();
