How can PHP be used to create a calendar script for managing events and reminders?

To create a calendar script for managing events and reminders using PHP, we can utilize PHP's date and time functions to display a calendar view and store events in a database. We can also use HTML forms to allow users to add, edit, and delete events.

<?php
// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "calendar_db";

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

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Display calendar
echo "<h2>Calendar</h2>";

// Display events from database
$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 "0 results";
}

// Add event form
echo "<h2>Add Event</h2>";
echo "<form action='add_event.php' method='post'>";
echo "Event Name: <input type='text' name='event_name'><br>";
echo "Event Date: <input type='date' name='event_date'><br>";
echo "<input type='submit' value='Add Event'>";
echo "</form>";

$conn->close();
?>
