What are some best practices for integrating PHP, MySQL, and Apache in a forum server to ensure optimal performance and functionality?

To ensure optimal performance and functionality when integrating PHP, MySQL, and Apache in a forum server, it is important to properly optimize database queries, use caching mechanisms, and implement efficient coding practices. Additionally, utilizing indexes on frequently queried columns and ensuring proper server configuration can help improve overall performance.

// Example of optimizing a database query in PHP using MySQL
$query = "SELECT * FROM posts WHERE category = 'PHP' ORDER BY date DESC LIMIT 10";
$result = mysqli_query($connection, $query);

// Loop through the results
while ($row = mysqli_fetch_assoc($result)) {
    // Display post content
    echo $row['content'];
}
