What specific PHP skills are necessary for creating a device rental system?

To create a device rental system in PHP, you will need skills in database management, user authentication, form handling, and session management. These skills will allow you to create a system where users can browse available devices, rent them, and manage their rentals. 

// Sample PHP code for creating a device rental system

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

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

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

// User authentication
session_start();

if(!isset($_SESSION['user_id'])) {
    header("Location: login.php");
    exit();
}

// Form handling
if($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process rental request
    $device_id = $_POST['device_id'];
    $user_id = $_SESSION['user_id'];
    
    // Insert rental record into database
    $sql = "INSERT INTO rentals (device_id, user_id) VALUES ('$device_id', '$user_id')";
    
    if ($conn->query($sql) === TRUE) {
        echo "Rental successful!";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}

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