What are the best practices for managing PHP extensions and modules to avoid issues like missing templates?

Issue: Missing templates can occur when PHP extensions or modules are not properly managed, leading to errors in loading necessary files for the application to run smoothly. To avoid this issue, it is important to ensure that all required extensions and modules are properly installed and configured in the PHP environment. Code snippet:

// Check if the required extension is loaded
if (!extension_loaded('mysqli')) {
    die('The mysqli extension is not loaded. Please make sure it is properly installed and configured.');
}
