PHP cookie 問題

小弟最近用PHP寫一個網站，現正寫有關login 部份，但我不知道是甚麼原因令這部份未能完成。 以下是我所寫的code
<?

include("CONNECT.php");

$UN = "test";

$PWD = "test";

$result= mysql_query("select * from user_info where u='$UN' and p='$PWD'");

$number = mysql_num_rows($result);


if ($number == 0)

{
echo "登入失敗!!找不到這個帳號或密碼!!";

exit;

}

elseif ($number > 0)

{
$FO = mysql_fetch_object($result);

setcookie ("LN", $UN, time()+(60*60*24));


if(isset($_COOKIE['LN']))


print "<p>OK</p>";

else

print "<p>Not OK</p>";

}

?>

就我自己所看我完全看不出那裡出了問題。請問會是web hosting 的問題嗎? 因為我用的是免費的web hosting ([url]www.700megs.com[/url], [url]www.free-site-host.com[/url])，若果是這樣的話有別的web hosting 可以提供嗎? 若果不是，那會是甚麼問題呢? 請指教，謝謝!

Cookie = data stored in brower; to be set by 1) javascript or 2) server
and will be sent to server when requesting new page . Therefore 
$_COOKIE['LN'] will contain value until you reload the server page.
