PHP Snippet: Check if code is running on a production environment

function isLive($liveTld = ".de")
{
       $homeUrl = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS']
       === 'on' ? "https" : "http")."://$_SERVER[HTTP_HOST]";

$returnMe = false;
if ( (!(strpos($homeUrl, ".local") !== false)) && (!(strpos($homeUrl, ".intra") !== false)) && (!(strpos($homeUrl, "stage") !== false)) && (!(strpos($homeUrl, "staging") !== false)) && (strpos($homeUrl, $liveTld) !== false) ) { $returnMe = true; }
return $returnMe; }

Get the clients IP address

$clientIpAdress = isset($_SERVER['HTTP_CLIENT_IP'])?$_SERVER['HTTP_CLIENT_IP']:isset($_SERVER['HTTP_X_FORWARDED_FOR'])?$_SERVER['HTTP_X_FORWARDED_FOR']:$_SERVER['REMOTE_ADDR'];

Do *not* use this on it’s own for security purposes!
