help on cookies please

I'm new to this whole PHP thing, but heres my problem using w2k, apache 1.3.? and php4 and IE5 basically whaat i want to know is how to accesss a cookie's value from localhost, that is both server and browser are on the same computer? I use setcookie("testcookie","test", time()+360) and the cookie is placed (it shows up in my temp inet files) but i can't retrieve the data. I should just be able to use '$testcookie' to get the value 'test' right? no value shows up. I don't get an 'undefined variable' error, its just an empty value. what am i doing wrong? thanks in advance! chris
