What are some best practices for handling sessions in PHP to avoid session-related errors?

One common issue with handling sessions in PHP is the potential for session-related errors such as session hijacking or data corruption. To avoid these errors, it is recommended to use secure session handling techniques, such as setting session cookie parameters, regenerating session IDs, and validating session data. 

// Start a secure session
session_start([
    'cookie_lifetime' => 86400, // Session cookie expires in 24 hours
    'cookie_secure' => true, // Only send cookies over HTTPS
    'cookie_httponly' => true // Prevent access to session cookies via JavaScript
]);

// Regenerate session ID to prevent session fixation
session_regenerate_id(true);

// Validate session data before using it
if(isset($_SESSION['user_id'])) {
    $user_id = $_SESSION['user_id'];
    // Use $user_id in your application
} else {
    // Handle session data validation error
}
