note 92412 added to function.getenv

A function returning the remote adress of the visiting browser could look like this: function getIPfromXForwarded() { $ipString=@getenv("HTTP_X_FORWARDED_FOR"); $addr = explode(",",$ipString); return $addr[sizeof($addr)-1]; } Note that some adresses are followed by a whitespace and ip2long(getIPfromXForwarded()) would not return the expected result. Make use of trim() in your scripts, either in the function itself, or the surrounding space of the caller.
