Question 13
If you set a cookie with either setcookie() or header(), you can immediately
check to see whether the client accepted it.
A. True, you can check the $_COOKIE superglobal array to see if it contains the
value you set.
B. True, but only if register_globals is enabled.
C. False, you can only use setcookie() if you need to test for acceptance.
Using header() does not work.
D. False, you must wait until you receive another HTTP request to determine
whether it includes the Cookie header.
