Cookie question

[benny_g]

I am setting a cookie with name that depends on a variable.

$PollID = 3;
setcookie("Poll" . $PollID, "Y", time()+ "604800");

So that the cookie is names Poll3 and has a value of "Y".

I want to check for the cookie from a function such as:

function check_cookie($PollID) {
code for checking cookie
}

PollID = 3;
check_cookie($PollID);

I want to be able to join "$Poll" and $PollID and then check whether the resulting variable name exists or has any data in it.

Is this possible?

yes it is.

if(!empty($_COOKIE[$PollID])) {
echo "alredy voted";
}

I need a way of getting the below example to work:

function check_cookie($PollID) {

if ($_COOKIE["Poll" . $PollID] == "Y") {
print("Cookie has value Y");
}

}

$PollID = "3";
check_cookie($PollID);
