What are the best practices for structuring SQL queries in PHP to handle date-based filtering of events?

When filtering events based on dates in SQL queries in PHP, it is best to use prepared statements to prevent SQL injection attacks. To structure the queries effectively, use placeholders for the date values and bind the actual date values to the placeholders. This helps ensure that the queries are secure and efficient. 

// Assuming $startDate and $endDate are the date range for filtering events

// Establish a database connection
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare the SQL query with placeholders for the date range
$stmt = $pdo->prepare("SELECT * FROM events WHERE event_date BETWEEN :start_date AND :end_date");

// Bind the actual date values to the placeholders
$stmt->bindParam(':start_date', $startDate);
$stmt->bindParam(':end_date', $endDate);

// Execute the query
$stmt->execute();

// Fetch the results
$events = $stmt->fetchAll(PDO::FETCH_ASSOC);

// Loop through the events and do something with them
foreach ($events as $event) {
    // Do something with each event
}
