What are the best practices for handling IP addresses and server time in PHP scripts to ensure accurate functionality?

When handling IP addresses in PHP scripts, it's important to use the proper functions to retrieve and validate the IP address. This ensures that the IP address is accurate and can be used safely in your script. Similarly, when working with server time in PHP scripts, it's recommended to set the correct timezone and use the appropriate functions to manipulate and display time accurately. 

// Get and validate the user's IP address
$user_ip = filter_var($_SERVER['REMOTE_ADDR'], FILTER_VALIDATE_IP);

// Set the timezone to your desired location
date_default_timezone_set('America/New_York');

// Get the current server time
$server_time = date('Y-m-d H:i:s');
