From my understanding $_COOKIE gives me all the cookies in a user's browser.
But when I do
var_dump($_COOKIE);
I get the following:
Array
(
[wp-settings-1] => m8=o&m2=o&m5=o&m4=o&m3=o&m1=o&m7=o&m0=o
[wp-settings-time-1] => 1329859655
[PHPSESSID] => ST88bLB7PE5S9BbY5oXxLgDIcas
)
This list does not match the list I see in the browser. For example, PHPSESSID is not in the list of cookies in my browser. Am I accessing the wrong variable?
Thanks.

Accessing Cookies with PHP Simplest way is to use either $_COOKIE or $HTTP_COOKIE_VARS variables. Following example will access all the cookies set in above example. You can use isset() function to check if a cookie is set or not.
You can use the print_r or var_dump function to check all available cookies for debugging purposes. print_r( $_COOKIE ); It's that easy to read cookies in PHP!
With PHP, you can both create and retrieve cookie values. The name of the cookie is automatically assigned to a variable of the same name. For example, if a cookie was sent with the name "user", a variable is automatically created called $user, containing the cookie value.
A cookie is a piece of data from a website that is stored within a web browser that the website can retrieve at a later time. Cookies are used to tell the server that users have returned to a particular website.
As mentioned $_COOKIE only gives you cookies for the current domain/path. You cannot see all cookies in a browser. You can see how this works if you ever sniff/view HTTP packets. When you make an HTTP request, the browser sends cookies to the server. This page has some excellent examples of what that HTTP traffic looks like.
