php $_COOKIE isset

I am using this code to set a cookie and then see if they exist

setcookie("token", "value", time()+60*60*24*100, "/");
setcookie("secret", "value", time()+60*60*24*100, "/");
setcookie("key", "value", time()+60*60*24*100, "/");

if (!isset($_COOKIE['token']) || !isset($_COOKIE['secret']) || !isset($_COOKIE['key'])) {

// do something because one of the cookies were not set

}

Even though all three of the cookies were set in my browser, it still runs the if() statement. Via the process of elimination I have discovered the middle cookie !isset($_COOKIE['secret']) seems to cause the if() statement to run even though the cookie secret was set in my browser. The script says it has not been set when I look at my browser and it has been set. Can you think of any reason why php is saying it wasn't set?

as my testing,we can't use cookies in same time.if you set cookies. you need to reload page to grab those. put like this 

if (!isset($_COOKIE['token'])) {
    setcookie("token", "value", time()+60*60*24*100, "/"); //this set cookies for first time
}

}

setcookie only defines a cookie to be sent along with the rest of the HTTP headers, and they can be accessed on the next page load with the $_COOKIE. With your code, the HTTP headers are not be sent.

You just need setcookie when a cookie is not set. Like:

if (!isset($_COOKIE['token'])) {
    setcookie("token", "value", time()+60*60*24*100, "/");
}
