How can a PHP developer efficiently implement a room booking system for a school with multiple users and various restrictions?

To efficiently implement a room booking system for a school with multiple users and various restrictions, the PHP developer can create a database schema to store room availability, user bookings, and restrictions. They can then develop a web application that allows users to search for available rooms based on their restrictions, book rooms, and manage their bookings. Additionally, the developer can implement user authentication and authorization to ensure only authorized users can book rooms. 

// Code snippet for creating a room booking system in PHP

// Database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "room_booking_system";

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

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

// Room booking functionality
function bookRoom($userId, $roomId, $date) {
    // Check if room is available on the given date
    // Check if user has any restrictions for booking this room
    // If available and no restrictions, insert booking into database
    $sql = "INSERT INTO bookings (user_id, room_id, date) VALUES ('$userId', '$roomId', '$date')";
    if ($conn->query($sql) === TRUE) {
        echo "Room booked successfully!";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}

// User authentication and authorization
function authenticateUser($username, $password) {
    // Check if username and password match in the database
    // Return true if authenticated, false otherwise
}

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