How can developers troubleshoot and debug session-related issues in PHP?

Session-related issues in PHP can be troubleshooted and debugged by checking if the session is properly started, ensuring session variables are set and accessed correctly, and verifying the session configuration in php.ini. Additionally, developers can use session debugging tools like session_id() and session_status() to track session data and status. 

// Start the session
session_start();

// Set session variables
$_SESSION['user_id'] = 123;

// Access session variables
$user_id = $_SESSION['user_id'];

// Check session status
if(session_status() === PHP_SESSION_ACTIVE) {
    echo 'Session is active';
} else {
    echo 'Session is not active';
}
