How can the PHP configuration settings related to session handling impact the behavior of session variables in a script?

The PHP configuration settings related to session handling, such as session.save_path, session.gc_maxlifetime, and session.cookie_lifetime, can impact the behavior of session variables in a script by affecting how sessions are stored, how long they are kept active, and how cookies are managed. To ensure proper session handling, it is important to configure these settings appropriately in the php.ini file or using ini_set() function in your script. 

// Set the session save path
session_save_path("/path/to/session/directory");

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

// Set the session cookie lifetime
ini_set('session.cookie_lifetime', 0);

// Start the session
session_start();

// Your PHP script code here
