RE: [PHP] HTTP_X_FORWARDED_FOR?

> Okay, thanks. 'Cause I mean, the REMOTE_ADDR is still there. So you > mean that the HTTP_X_FORWARDED_FOR isn't working while I'm working localhost? REMOTE_ADDR contains the IP of the computer that requested your page. If it was a proxy doing the request, you'll have the proxy's IP in this variable, and the IP of the computer that requested the page from the proxy will be in HTTP_X_FORWARDED_FOR. This means the best way to grab an IP is with a a function like this: <?php function getIP () { if (getenv(HTTP_X_FORWARDED_FOR)) { $ip = getenv(HTTP_X_FORWARDED_FOR); } else { $ip = getenv(REMOTE_ADDR); } return $ip; } ?> I'm unsure what happens with multiple proxies, and I'd be interested to know - do you get an array of HTTP_X_FORWARDED_FORs? Do you just get the first or the last? Cheers Jon
