What are some common features of a PHP-based scheduler or calendar application?

Common features of a PHP-based scheduler or calendar application include the ability to add, edit, and delete events, display events in a calendar view, set reminders for events, and allow users to share their calendars with others. 

// Example PHP code snippet for a basic calendar application

// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "calendar_app";

$conn = new mysqli($servername, $username, $password, $dbname);

// Display events in a calendar view
$sql = "SELECT * FROM events";
$result = $conn->query($sql);

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

// Add new event
if(isset($_POST['submit'])) {
    $event_name = $_POST['event_name'];
    $event_date = $_POST['event_date'];

    $sql = "INSERT INTO events (event_name, event_date) VALUES ('$event_name', '$event_date')";
    $conn->query($sql);
    header("Location: calendar.php");
}

// Delete event
if(isset($_GET['delete'])) {
    $event_id = $_GET['delete'];

    $sql = "DELETE FROM events WHERE event_id=$event_id";
    $conn->query($sql);
    header("Location: calendar.php");
}

// Edit event
if(isset($_POST['update'])) {
    $event_id = $_POST['event_id'];
    $event_name = $_POST['event_name'];
    $event_date = $_POST['event_date'];

    $sql = "UPDATE events SET event_name='$event_name', event_date='$event_date' WHERE event_id=$event_id";
    $conn->query($sql);
    header("Location: calendar.php");
}

$conn->close();
