What are some best practices for structuring PHP code to display forum threads and replies efficiently?

Issue: When displaying forum threads and replies, it is important to structure the PHP code efficiently to ensure optimal performance. One way to achieve this is by using a combination of loops and conditional statements to fetch and display the necessary data in a organized manner.

// Example PHP code snippet for displaying forum threads and replies efficiently

// Assuming $threads is an array of thread objects and $replies is an array of reply objects

foreach ($threads as $thread) {
    echo "<h2>{$thread->title}</h2>";
    echo "<p>{$thread->content}</p>";

    foreach ($replies as $reply) {
        if ($reply->thread_id == $thread->id) {
            echo "<div class='reply'>";
            echo "<p>{$reply->content}</p>";
            echo "</div>";
        }
    }
}
