PHP 8.1 session not persisting after redirect with custom session handler
I'm dealing with I've been working on this all day and I'm sure I'm missing something obvious here, but I'm working with an scenario with session persistence in PHP 8.1 when I use a custom session handler along with a redirect. I've implemented a class that uses Redis as the session storage, and while the session data is saved correctly, it doesn't seem to continue after a redirect operation. Here’s a portion of my session handling code: ```php class RedisSessionHandler implements SessionHandlerInterface { private $redis; public function __construct() { $this->redis = new Redis(); $this->redis->connect('127.0.0.1', 6379); } public function open($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 this automatically return true; } } $handler = new RedisSessionHandler(); session_set_save_handler($handler, true); session_start(); $_SESSION['user'] = 'JohnDoe'; header('Location: next_page.php'); die(); ``` After the redirect to `next_page.php`, when I try to access `$_SESSION['user']`, it returns `null`. I've ensured that session.auto_start is set to 0 in my `php.ini`, and I've also checked that Redis is running and available. I tried to debug the `write` method to confirm that the session data is being written, and it is. However, upon redirecting, it seems like the session isn't being read correctly on the next page. I've also experimented with calling `session_write_close()` before the redirect to see if it would help, but that didn't make a difference either. Is there something I'm missing in the session handling process or the redirect that could cause this scenario with PHP 8.1? Any insights would be appreciated! For context: I'm using Php on Windows. Any help would be greatly appreciated! My development environment is Windows. The stack includes Php and several other technologies. I'm using Php 3.11 in this project.
