implementing Custom Session Handler in PHP 8.0 and Redis for Session Management
I'm deploying to production and I'm trying to implement I'm not sure how to approach After trying multiple solutions online, I still can't figure this out... I'm having trouble implementing a custom session handler in PHP 8.0 using Redis for session management. I set up my Redis connection and implemented the required methods, but sessions don't seem to continue properly. Here's what I've done so far: I created a `SessionHandler` class that implements `SessionHandlerInterface`: ```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; } } ``` I then initialize Redis and set this custom session handler: ```php $redis = new Redis(); $redis->connect('127.0.0.1', 6379); $handler = new RedisSessionHandler($redis); session_set_save_handler($handler, true); session_start(); ``` However, when I try to store session data by doing something like this: ```php $_SESSION['username'] = 'test_user'; ``` I notice that after a page refresh, the session data is lost. I also see a warning in my logs: ``` Warning: session_write_close(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (path: ) in ... ``` I’ve checked that `session.save_handler` is set to `user` in my `php.ini`, but it seems like PHP is trying to write to the default file handler instead. Could the scenario be related to how I'm setting the session handler, or is there something I might be overlooking with the Redis connection? Any insights would be greatly appreciated! Has anyone else encountered this? This is my first time working with Php 3.11. Thanks in advance! I'm working on a application that needs to handle this.
