How can one configure a server to only provide information to a specific IP address in PHP?

To configure a server to only provide information to a specific IP address in PHP, you can use the $_SERVER['REMOTE_ADDR'] variable to check the IP address of the client requesting the information. If the IP address matches the desired address, you can proceed with providing the information. If not, you can deny access by returning a 403 Forbidden status code. 

$allowed_ip = '192.168.1.1'; // Specify the allowed IP address

if ($_SERVER['REMOTE_ADDR'] != $allowed_ip) {
    http_response_code(403);
    die('Access Forbidden');
}

// Proceed with providing the information to the allowed IP address
