What are the best practices for handling and analyzing IP address data without using MySQL in PHP?

When handling and analyzing IP address data in PHP without using MySQL, it is important to properly validate and sanitize the input to prevent any security vulnerabilities. One way to achieve this is by using PHP's filter_var function with the FILTER_VALIDATE_IP flag. Once the IP address data is validated, you can then perform any necessary analysis or manipulation on the data. 

// Validate and sanitize IP address input
$ip_address = filter_var($_POST['ip_address'], FILTER_VALIDATE_IP);
if ($ip_address === false) {
    // Handle invalid IP address input
    echo "Invalid IP address";
} else {
    // Perform analysis or manipulation on the IP address data
    echo "Valid IP address: " . $ip_address;
}
