Are there any best practices for efficiently integrating database query results into a PHP calendar generation script?

When integrating database query results into a PHP calendar generation script, it is important to efficiently handle the data retrieval and processing to ensure optimal performance. One best practice is to fetch only the necessary data from the database and organize it in a way that can easily be integrated into the calendar generation logic. Using appropriate data structures and algorithms can help streamline the process and improve the overall efficiency of the script.

// Assuming $db is your database connection and $query is your SQL query to retrieve calendar events
$result = $db->query($query);

// Fetch the query results into an associative array
$events = $result->fetch_all(MYSQLI_ASSOC);

// Loop through the events and integrate them into the calendar generation logic
foreach ($events as $event) {
    // Process each event and add it to the calendar
    // Example: echo "<div>{$event['title']}</div>";
}
