podrias usar esta funcion para saber el navegador que usan.,.. y luego con el resultado hacer lo que pides... no es complicado
Código PHP:
function FUNC_brouserUsr(){ //echo FUNC_brouserUsr();
if((ereg("Nav", $_SERVER["HTTP_USER_AGENT"])) || (ereg("Gold", $_SERVER["HTTP_USER_AGENT"])) || (ereg("X11", $_SERVER["HTTP_USER_AGENT"])) || (ereg("Mozilla", $_SERVER["HTTP_USER_AGENT"])) || (ereg("Netscape", $_SERVER["HTTP_USER_AGENT"])) AND (!ereg("MSIE", $_SERVER["HTTP_USER_AGENT"]) AND (!ereg("Konqueror", $_SERVER["HTTP_USER_AGENT"])))) $browser = "Netscape";
elseif(ereg("MSIE", $_SERVER["HTTP_USER_AGENT"])) $browser = "MSIE";
elseif(ereg("Lynx", $_SERVER["HTTP_USER_AGENT"])) $browser = "Lynx";
elseif(ereg("Opera", $_SERVER["HTTP_USER_AGENT"])) $browser = "Opera";
elseif(ereg("Netscape", $_SERVER["HTTP_USER_AGENT"])) $browser = "Netscape";
elseif(ereg("Konqueror", $_SERVER["HTTP_USER_AGENT"])) $browser = "Konqueror";
elseif((eregi("bot", $_SERVER["HTTP_USER_AGENT"])) || (ereg("Google", $_SERVER["HTTP_USER_AGENT"])) || (ereg("Slurp", $_SERVER["HTTP_USER_AGENT"])) || (ereg("Scooter", $_SERVER["HTTP_USER_AGENT"])) || (eregi("Spider", $_SERVER["HTTP_USER_AGENT"])) || (eregi("Infoseek", $_SERVER["HTTP_USER_AGENT"]))) $browser = "Bot";
