How can a poorly configured server impact the performance and functionality of a PHP script, particularly in relation to session management and data processing?

A poorly configured server can impact the performance and functionality of a PHP script by causing slow response times, timeouts, or errors in session management and data processing. To solve this, ensure that the server has enough resources allocated to handle the script's requirements, optimize server settings for PHP, and regularly monitor and tune the server for optimal performance. 

// Example code snippet for optimizing session management in PHP
ini_set('session.gc_maxlifetime', 3600); // Set session expiration time to 1 hour
ini_set('session.cookie_lifetime', 0); // Set session cookie to expire when the browser is closed
session_set_cookie_params(0, '/', '.example.com', true, true); // Set cookie parameters for cross-subdomain sessions
session_start(); // Start the session
