What strategies can be implemented to troubleshoot and debug issues related to session handling and cookie management in PHP?

Session handling and cookie management issues in PHP can be troubleshooted and debugged by checking for common mistakes such as incorrect session configuration, expired cookies, or conflicting session variables. To solve these issues, ensure that session_start() is called at the beginning of each PHP script, set appropriate session configurations in php.ini, and check for any errors in cookie settings.

// Ensure session_start() is called at the beginning of each PHP script
session_start();

// Set appropriate session configurations in php.ini
// For example, adjust session.gc_maxlifetime to control session expiration time

// Check for any errors in cookie settings
// Verify that cookies are being set correctly and not conflicting with session variables
