Question

I need to add an if statement on top of my php script in order to check the ip of the script invoker:

if (invoker_ip = "123.123.123.123") {
    .. code here ..
}

the script is just a script.php file on my server

thanks

Answer 1

Use :

$invoker_ip = $_SERVER['REMOTE_ADDR'];

Nevertheless this value will not be relevant if user is behind a proxy.
The real ip probably can be found in HTTP header like HTTP_CLIENT_IP or HTTP_X_FORWARDED_FOR but can’t be trusted. (header are easy to modify)
