Are there best practices for optimizing PHP systems to handle high levels of traffic and page views?

To optimize PHP systems to handle high levels of traffic and page views, it is essential to implement caching mechanisms, optimize database queries, use efficient coding practices, and utilize a content delivery network (CDN) to distribute content. Additionally, scaling resources such as servers and databases can help accommodate increased traffic demands. 

// Example of implementing caching in PHP using memcached
$memcached = new Memcached();
$memcached->addServer('localhost', 11211);

$key = 'cached_data';
$data = $memcached->get($key);

if (!$data) {
    // If data is not cached, fetch it from the database
    $data = fetchDataFromDatabase();

    // Store the data in the cache for future use
    $memcached->set($key, $data, 3600); // Cache for 1 hour
}

// Use the cached data for rendering the page
echo $data;
