Finally, the following code calls to the appropriate position
IP Address: <? Php echo tangrui_getip ();?>
Location: <php echo tangrui_getLocation ();??>
The type of browser: <php echo GetBrowser ();??>
Browser language: <php echo GetLang ();??>
Operating System: <? Php echo GetOs ();?>
Current time: <? Php echo $ showtime = date ( "Ymd H: i: s");?>
