I'm wondering if anyone has experience with I've hit a wall trying to I'm stuck on something that should probably be simple. I'm working with an scenario with session management in my Symfony 5 application using PHP 8.1. After calling `session_start()`, the session data appears to be lost after the first request. I've configured my session handler properly and verified that sessions are being started. Here’s a snippet of the code I’m using in my controller: ```php public function index(Request $request) { session_start(); // Starting the session if (!isset($_SESSION['counter'])) { $_SESSION['counter'] = 1; } else { $_SESSION['counter']++; } return new Response('Counter: ' . $_SESSION['counter']); } ``` When I visit the endpoint, the counter starts at 1, as expected, but upon refreshing, it always returns 1 instead of incrementing. I've also checked that the session data is correctly being written in `var_dump($_SESSION);` right after I set it, and it shows as expected. I've added the following to my `php.ini` file to ensure proper session management: ``` session.save_handler = files session.save_path = "/tmp" session.gc_maxlifetime = 1440 ``` I’ve tried switching the session storage to a database without success, and I’ve also verified that the necessary permissions for the session save path are set correctly. Is there something I’m missing in terms of Symfony’s session handling, or is there a specific configuration for PHP 8.1 that might be affecting session persistence? I recently upgraded to Php 3.10. Am I missing something obvious? Any examples would be super helpful. I recently upgraded to Php 3.11. Any suggestions would be helpful.
