{
echo "you are not login or you idle for 10minutes before. Pls relogin";
}

try this u will have to edit for ur session data

setcookie("phpsessid",$_COOKIE['phpsessid'],strtotime("+10 minutes"),"/");

if not works. you can use

setcookie(session_name(), $_COOKIE[session_name()], time() + 600, "/"); 

;-) or, use simply

ini_set("session.gc_maxlifetime", 10*60);
