一旦用户通过身份验证，我就序列化类对象并将其存储在 session 中。但是，即使在使用 unserialize() 之后，我似乎也无法打印它的输出。
创建 session 变量:
if(!isset($_SESSION['myObj']) && empty($_SESSION['myObj'])) {
$myObj = new User($row['user_id'], $row['username'], $row['user_level']);
$_SESSION['username']= $myObj->usr_name;
$s_Obj = serialize($myObj);
$_SESSION['myObj'] = $s_Obj;
从不同的页面访问，无输出:
$sObj = $_SESSION['Obj'];
$myObj = unserialize($s_Obj);
echo $myObj->usr_name;
但是这有效，所以我的类(class)没有任何问题。我还在两个页面中使用了 session_start()。
echo $_SESSION['username'];
类用户:
<?php
class User{
public $usr_id;
public $usr_name;
public $usr_level;
public $last_access_login;
public function __construct($id, $usr_name, $usr_level) {
$this->usr_id = $id;
$this->usr_name = $usr_name;
$this->usr_level = $usr_level;
$this->last_access_login = date("F d Y H:i:s.",time());
}
}
?>
编辑:
这是我的转储
