What are the best practices for handling changes in server configurations that affect PHP functionality?

When server configurations change and affect PHP functionality, it is important to review the changes and update the PHP code accordingly. This may involve adjusting settings in the php.ini file, modifying PHP code to adapt to new server configurations, or utilizing server-side scripts to handle specific configurations.

// Example: Adjusting PHP settings in php.ini file
// Increase memory_limit setting to handle larger requests
ini_set('memory_limit', '256M');
