What role does caching play in the differences between local environments like XAMPP and live servers when it comes to session handling in PHP?

When it comes to session handling in PHP, caching can play a significant role in the differences between local environments like XAMPP and live servers. Caching can cause session data to be stored and retrieved differently, leading to inconsistencies between the two environments. To address this issue, it is important to disable caching for session data in PHP to ensure consistent behavior across different environments.

// Disable caching for session data
session_cache_limiter('nocache');

// Start the session
session_start();
