How can developers troubleshoot and debug session-related issues in PHP when transitioning between different hosting providers?

When transitioning between different hosting providers, developers may encounter session-related issues in PHP due to differences in server configurations. To troubleshoot and debug these issues, developers can start by checking if session variables are being properly set and retrieved. They can also verify if session.save_path is correctly configured in the php.ini file. Additionally, developers can use session debugging tools like session_id() and session_status() to track session behavior. 

// Check if session variables are being properly set and retrieved
session_start();
$_SESSION['test'] = 'example';
echo $_SESSION['test'];

// Verify session.save_path configuration
echo session_save_path();

// Use session debugging tools
echo session_id();
echo session_status();
