如何从不同文件中的类中获取变量的值?

我有一个user.php(类),login.php和index.php。当我在index.php中提交表单时,表单操作转到login.php,此文件使用User Class来验证是否存在尝试登录的人。如果为true,则再次重定向到index.file。但我想在用户登录时将用户full_name写入index.php。但是我不能从课堂上获取full_name。

注意:在require_once中,代码中包含必要的文件,如database.php,session.php,functions.php等。因此,它们没有错误,我的函数也没有错误。我想要的是如何在用户登录时将full_name写入index.php。

这是user.php:

require_once $_SERVER['DOCUMENT_ROOT'].'/includes/database.php';

class User{

protected static $table_name="users";
protected static $db_fields = array('id', 'email', 'password', 'first_name',
'last_name');

public $id;
public $email;
public $password;
public $first_name;
public $last_name;

public function full_name() {
if(isset($this->first_name) && isset($this->last_name)) {
  return $this->first_name . " " . $this->last_name;
} else {
  return "";
 }
}

public static function verify($user, $email="", $password="") {
global $database;

$sql  = "SELECT * FROM users ";
$sql .= "WHERE email = '{$email}' ";
$sql .= "AND password = '{$password}' ";
$sql .= "LIMIT 1";
$result_array = self::find_by_sql($sql);

    if (!empty($result_array)) {
        $user->first_name =  $result_array['first_name'];
        $user->last_name =   $result_array['last_name'];
        return array_shift($result_array);
    } else {
        return false;
    }
 }  

$user = new User();
//User class continue but i inserted necessary parts. All functions in the class works.

这是login.php:

<?php require_once  $_SERVER['DOCUMENT_ROOT'].'/includes/initialize.php'; ?>
<?
if($session->is_logged_in()) {
redirect_to("index.php");

}

if (isset($_POST['submit'])) {

$email = trim($_POST['email']);
$password = trim($_POST['password']);


$found_user = User::verify($user,$email, $password);

if ($found_user) {
$session->login($found_user);

    redirect_to("index.php");

} else {

$message = "There is error about username/password";
echo $message;
}

} else {
$email = "";
$password = "";
} 
?>

这是index.php:

<?php require_once  $_SERVER['DOCUMENT_ROOT'].'/includes/initialize.php'; ?>

<?php

if($session->is_logged_in()) {
echo $user->full_name();

} else {
echo "No name";
}



?>

将full_name的输出保存到会话变量。然后可以调用它来重现名称。
