thanks people, but it still doesn't work, here's my updated test codes:
<?
SetCookie("Nazcausr", "dean", time()+3600, "", ".the-junkyard.net", 1);
?>
<?
echo $_cookie["Nazcausr"];
?>
still nothing, ugh, this makes me angry, I've always had a problem with cookies, and now no one on my site can log in๐
