PHP 8.2 - implementing Custom Session Handler and Serialization of Objects
I'm working with a question with my custom session handler in PHP 8.2 when trying to serialize an object for session storage. My custom handler implements `SessionHandlerInterface`, but when I attempt to store an object, it seems that the serialization process is failing silently. I have a class called `User` that contains properties and some methods, and I want to store an instance of this class in the session. However, when I try to access the session data, it throws an behavior stating `unserialize(): behavior at offset 0 of 123 bytes`. Here's a snippet of what my session handler looks like: ```php class SessionHandler implements SessionHandlerInterface { public function open($savePath, $sessionName) { // Initialize your database connection or whatever here return true; } public function close() { // Cleanup here return true; } public function read($sessionId) { // Fetch the session data from the database // Returning dummy data for testing return serialize(new User('JohnDoe', 30)); } public function write($sessionId, $data) { // Store session data in the database return true; } // Other methods like destroy, gc, etc. } ``` In my `User` class, I have: ```php class User { public $username; public $age; public function __construct($username, $age) { $this->username = $username; $this->age = $age; } } ``` When I try to start a session and set the user instance like this: ```php session_start(); $_SESSION['user'] = new User('JaneDoe', 25); ``` I'm not able to correctly read it back from the session. I suspect the serialization might not be handling the `User` object correctly. I also tried implementing the `Serializable` interface in my `User` class, but it hasn't resolved the scenario. Any insights on what might be going wrong here or what best practices I should follow for storing objects in sessions in PHP 8.2? I'm working with Php in a Docker container on Ubuntu 22.04. Cheers for any assistance!
