How can PHP beginners ensure that their dynamically generated pages are efficient and optimized for performance?

PHP beginners can ensure that their dynamically generated pages are efficient and optimized for performance by caching the output of expensive operations and database queries. This can help reduce the load on the server and speed up the rendering of the page. Additionally, they can minimize the use of external resources, such as third-party libraries or APIs, and optimize their code by avoiding unnecessary loops and function calls. 

// Example of caching the output of an expensive operation
$cacheKey = 'expensive_operation_cache';
if (!($output = getFromCache($cacheKey))) {
    $output = performExpensiveOperation();
    saveToCache($cacheKey, $output);
}
echo $output;
