Difficulty with serialized PHP session data not being recognized after migrating to a new server
I can't seem to get I'm experiencing issues with PHP session data after migrating my application from an old server to a new one. The sessions were previously serialized using the default method, but now when I try to access session variables, I get an empty array. I checked the session save path and ensured it has the correct permissions set, but I still encounter this question. Here's a snippet of the code where I set the session data: ```php session_start(); $_SESSION['user'] = [ 'id' => 1, 'name' => 'John Doe', 'email' => 'john.doe@example.com' ]; session_write_close(); ``` On the new server, I'm using PHP 8.0, and I confirmed that the session configuration in `php.ini` matches what it was on the old server. The relevant configuration is: ```ini session.save_handler = files session.save_path = "/tmp" session.serialize_handler = php ``` After migrating, I can see the session file is created in the `/tmp` directory, but accessing `$_SESSION` returns an empty array. I also tried using `session_id()` to verify that the session is consistent, and it returns the same ID as before. To debug this, I checked if the session files are readable, and they are. I attempted to use `session_start()` right before I access any session variables but it didn't help. Could it be an scenario with how PHP serializes sessions in different versions? Am I missing something with session migration, or is there a known scenario with session data handling in PHP 8.0? Any insights would be greatly appreciated! I'm coming from a different tech stack and learning Php. Any ideas what could be causing this?
