In the context of PHP programming, how can the integration of DATE_ADD and INTERVAL functions in SQL queries enhance the filtering and display of upcoming events while excluding past events?

To filter and display upcoming events while excluding past events in PHP programming, you can use the DATE_ADD and INTERVAL functions in SQL queries. By adding an INTERVAL to the current date using DATE_ADD, you can filter out events that have already occurred. This allows you to only display events that are in the future. 

// Connect to the database
$conn = new mysqli($servername, $username, $password, $dbname);

// Get the current date
$currentDate = date('Y-m-d');

// Query to select upcoming events
$sql = "SELECT * FROM events WHERE event_date > DATE_ADD('$currentDate', INTERVAL 1 DAY)";

$result = $conn->query($sql);

// Display upcoming events
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "Event: " . $row["event_name"] . " Date: " . $row["event_date"] . "<br>";
    }
} else {
    echo "No upcoming events";
}

// Close the connection
$conn->close();
