在PHP中检索Cookie值

Question

I'm trying to retrieve the cookie's value by simply calling its indexed position in the array, which is 1. However, I'm getting an error message saying 1 is an undefined offset? When I know for a fact it is in position 1. Am I missing something??

$query = "SELECT * FROM basketID" . $_COOKIE[1];

I've set the cookie like this

setcookie('visitUid',$uid,time()+60*60*24*7, '/');

$uid is a randomly generated number btw.

$_COOKIE['visitUid']是您要寻找的
