note 32935 added to function.getenv

This last example for fetching ip-adresses is not "full-proof" though, cause some ip adresses still return "unknown". This didn't happen (for exactly same "user" / ip-address) with the original (Anders Winther's) version, but for some reason his code has been deleted :( ---- Manual Page -- http://www.php.net/manual/en/function.getenv.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+32935 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+32935&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+32935&report=yes
