php sessions redis serialization PHP

I've looked through the documentation and I'm still confused about I need some guidance on I can't seem to get Hey everyone, I'm running into an issue that's driving me crazy. I'm working on a PHP 8.1 application where I've implemented a custom session handler to store session data in a Redis database. However, I'm working with an scenario where complex objects stored in the session are not being serialized correctly, leading to loss of data on subsequent requests. My session handler looks like this: ```php class RedisSessionHandler implements SessionHandlerInterface { private $redis; public function __construct($redis) { $this->redis = $redis; } public function open($savePath, $name) { return true; } public function close() { return true; } public function read($id) { return $this->redis->get($id) ?: ""; } public function write($id, $data) { return $this->redis->set($id, $data); } public function destroy($id) { return $this->redis->del($id); } public function gc($maxlifetime) { return true; } } ``` When I store an object like so: ```php $_SESSION['user'] = new User('John', 'Doe'); ``` I later attempt to retrieve it, but I only get an empty object or an behavior when accessing its properties. I've confirmed that the `User` class implements `Serializable`, but it seems the session data is not being serialized as expected. I also tried using `json_encode` before storing the data: ```php $this->redis->set($id, json_encode($data)); ``` However, this results in an behavior when trying to unserialize the session data. I've checked the Redis server and the data is being written, but it appears to be empty or corrupted upon retrieval. Any thoughts on how to ensure that complex objects can be stored and retrieved correctly in a custom session handler? I'm using PHP 8.1, Redis 6, and the `predis/predis` library for Redis interactions. My development environment is Windows. How would you solve this? Has anyone else encountered this? I'd love to hear your thoughts on this. The project is a REST API built with Php. This is happening in both development and production on Windows 11. What's the correct way to implement this?
