Is it possible to take site address on which user was before entering my site

 

yes!! check your $_SERVER variable. youll be pleased with the information you get there print_r($_SERVER);

 

$_SERVER["refer"] I think,

 

$_SERVER['HTTP_REFERER']

Code (markup):

Whew, I finally got it to display as uppercase.
