What are some common pitfalls when using PHP for home automation projects like Smart Home setups?

One common pitfall when using PHP for home automation projects is security vulnerabilities, such as not properly sanitizing user input or using outdated libraries. To solve this, always validate and sanitize user input, use secure coding practices, and keep libraries updated to prevent security breaches.

// Example of validating and sanitizing user input
$user_input = $_POST['user_input'];
$clean_input = filter_var($user_input, FILTER_SANITIZE_STRING);
