How can developers troubleshoot issues with PHP session handling and configuration variables like session.gc_maxlifetime?

Issue: Developers can troubleshoot issues with PHP session handling and configuration variables like session.gc_maxlifetime by checking the session configuration settings in the php.ini file and ensuring that the session.gc_maxlifetime value is set to an appropriate time interval. They can also use session_set_cookie_params() function to set the session cookie parameters in their PHP code.

// Set the session garbage collection lifetime to 1 hour
ini_set('session.gc_maxlifetime', 3600);

// Start the session
session_start();
