<?php

class MongoSessionHandler implements SessionHandlerInterface
{
    private $collection;

    public function __construct(\MongoDB\Collection $collection)
    {
        $this->collection = $collection;
    }

    public function open($savePath, $sessionName)
    {
        return true;
    }

    public function close()
    {
        return true;
    }

    public function read($sessionId)
    {
        $result = $this->collection->findOne(['_id' => $sessionId]);
        return $result ? $result['data'] : '';
    }

    public function write($sessionId, $sessionData)
    {
        $this->collection->updateOne(
            ['_id' => $sessionId],
            ['$set' => ['data' => $sessionData]],
            ['upsert' => true]
        );
        return true;
    }

    public function destroy($sessionId)
    {
        $this->collection->deleteOne(['_id' => $sessionId]);
        return true;
    }

    public function gc($maxLifetime)
    {
        $this->collection->deleteMany(['timestamp' => ['$lt' => (time() - $maxLifetime)]]);
        return true;
    }
}

// Usage:

// Connect to MongoDB
$mongoClient = new \MongoDB\Client('mongodb://localhost:27017');

// Select a database and collection
$database = $mongoClient->selectDatabase('sessions');
$collection = $database->selectCollection('session_data');

// Create an instance of the custom session handler
$handler = new MongoSessionHandler($collection);

// Set the custom session handler
session_set_save_handler($handler, true);

// Start the session
session_start();

// Now you can use $_SESSION as usual
$_SESSION['custom_data'] = 'Hello, this is custom session data.';
