PHP 8.2 - Session data not persisting between requests when using custom session handler
I've spent hours debugging this and I've hit a wall trying to I keep running into I tried several approaches but none seem to work. I'm experiencing issues with session data not persisting between requests when using a custom session handler in PHP 8.2. I've implemented a custom session handler that stores session data in a Redis database. However, when I save data to the session in one request and try to access it in another, it seems to be lost. Here’s the relevant part of my session handler: ```php class RedisSessionHandler implements SessionHandlerInterface { private $redis; public function __construct($redis) { $this->redis = $redis; } public function open($savePath, $sessionName) { return true; } public function close() { return true; } public function read($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) { // Redis handles cleanup internally return true; } } ``` I register my session handler like this: ```php $redis = new Redis(); $redis->connect('127.0.0.1', 6379); $handler = new RedisSessionHandler($redis); session_set_save_handler($handler, true); session_start(); ``` I can see that the session ID is being created correctly, and when I set a session variable like so: ```php $_SESSION['user_id'] = 123; ``` It appears to be stored in Redis. However, when I try to access it in another request: ```php session_start(); echo $_SESSION['user_id']; // This outputs nothing ``` I’ve also verified that Redis is working correctly by manually setting and retrieving key-value pairs. I’ve ensured that my PHP configuration has session.auto_start disabled and that session.use_cookies is enabled. I’d appreciate any insights on whether other configurations might be affecting session persistence or if there's something I've overlooked in the custom session handler implementation. Any advice would be greatly appreciated! My development environment is Linux. I recently upgraded to Php 3.10. Has anyone else encountered this? Is there a simpler solution I'm overlooking?
