What are some best practices for optimizing the performance of a news display system in PHP?

Issue: To optimize the performance of a news display system in PHP, it is important to minimize database queries, utilize caching mechanisms, and optimize code efficiency. 

// Example code snippet for optimizing news display system performance

// Use a single query to fetch all necessary news data
$news_query = "SELECT * FROM news_table ORDER BY date DESC LIMIT 10";
$news_result = mysqli_query($connection, $news_query);

// Store the fetched news data in an array for future use
$news_data = mysqli_fetch_all($news_result, MYSQLI_ASSOC);

// Implement caching to reduce database queries
$cache_key = 'news_cache';
if (!($news_data = getFromCache($cache_key))) {
    $news_data = fetchDataFromDatabase();
    setCache($cache_key, $news_data, $cache_expiry_time);
}

// Loop through the news data to display it on the webpage
foreach ($news_data as $news) {
    echo "<div class='news-item'>";
    echo "<h2>{$news['title']}</h2>";
    echo "<p>{$news['content']}</p>";
    echo "</div>";
}
