Are there any best practices for developing a Warenwirtschaftsprogramm with PHP and MySQL?

When developing a Warenwirtschaftsprogramm (inventory management program) with PHP and MySQL, it is important to follow best practices to ensure the efficiency, security, and scalability of the application. Some best practices include using prepared statements to prevent SQL injection attacks, sanitizing user input, implementing proper error handling, and optimizing database queries for performance. 

// Example of using prepared statements to insert data into a MySQL database

// Establish a connection to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "inventory_db";

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

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

// Prepare and bind the SQL statement
$stmt = $conn->prepare("INSERT INTO products (product_name, quantity, price) VALUES (?, ?, ?)");
$stmt->bind_param("sid", $product_name, $quantity, $price);

// Set parameters and execute the statement
$product_name = "Product A";
$quantity = 10;
$price = 50.00;
$stmt->execute();

echo "New record inserted successfully";

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