What are the best practices for ensuring PHP compatibility and functionality on a server?

To ensure PHP compatibility and functionality on a server, it is important to regularly update PHP to the latest stable version, enable error reporting to catch any issues, and utilize proper coding practices to avoid deprecated functions or features. Additionally, keeping an eye on server configurations, such as memory limits and execution time, can help optimize PHP performance. 

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Check PHP version
if (version_compare(PHP_VERSION, '7.4.0') < 0) {
    die('PHP version 7.4.0 or higher is required');
}

// Check for deprecated functions
if (function_exists('deprecated_function')) {
    trigger_error('deprecated_function is deprecated', E_USER_DEPRECATED);
}

// Check server configurations
echo ini_get('memory_limit');
echo ini_get('max_execution_time');
