无法使用PHP检索某些cookie

Question

I've got to be missing something simple, but this is driving me batty.

I'm setting a whole bunch of array cookies, like so:

setcookie("adjusted[$title]", $title, time() + 3600, "/", ".domain.com");

This works just fine, the cookies are being set and I can see them in the browser's cookie list.

However, I can't seem to read only certain values back out! I have no idea why. For example, I set this cookie:

adjusted[calldelivernow.net]

and I can see that is its name in Firefox's cookies page, the content is "calldelivernow.net". But all attempts to do this return false:

if(isset($_COOKIE["adjusted"]["calldelivernow.net"]))
    die("Cookie is set");

This is just one example of many, all under identical parameters just with different domain names. What on earth am I missing here? How can a cookie plainly exist in the browser, yet PHP not be able to read it?

Answer 1

Because you're not calling it by it's name correctly. Unlike form names, cookies do not get stacked to arrays.

Try $_COOKIE["adjusted[calldelivernow.net]"].
