Sometimes you want to grab the connecting web client's IP address in a PHP script. This is how:

if ( isset($_SERVER["REMOTE_ADDR"]) ) {
echo '' . $_SERVER["REMOTE_ADDR"] . ' ';
} else if ( isset($_SERVER["HTTP_X_FORWARDED_FOR"]) ) {
echo '' . $_SERVER["HTTP_X_FORWARDED_FOR"] . ' ';
} else if ( isset($_SERVER["HTTP_CLIENT_IP"]) ) {
echo '' . $_SERVER["HTTP_CLIENT_IP"] . ' ';
}

Twitter is over capacity again as I write. This is no big problem in itself. I can live without the constant stream of witty and insightful interruptions to my day. Hey, I might actually get some work done. But the problem is indicative of Twitter's failure to scale its infrastructure to meet demand. The service is free, so who am I to complain? They might do better if we were paying for the service.
