PHP error when trying to find cookie

I set a cookie this way

$id = 5; //just for clarification
setcookie("NAME", $id, time()+3600*24);

And look for it this way

$cookie = $_COOKIE["NAME"];

I check if this cookie is set (using: if(isset($cookie))) and it works perfectly.

The thing is, this code works only if the cookie is set, but if not, I get the following error

Notice: Undefined index: NAME in [path], line [line]

In some cases the cookie will not be set (naturally). Is there a way I can handle it?

$cookie = isset($_COOKIE["NAME"]) ? $_COOKIE["NAME"] : null;

and you can continue checking for isset($cookie) whenever you use the cookie

You need to check isset($_COOKIE["NAME"]) or array_has_key($_COOKIE, "name"); or something like that

Yes, by checking isset($_COOKIE['NAME']) before accessing it. Alternatively you can turn off that error message entirely (Not a good idea, it will be on by default on most servers usually). For that see the documentation. You would want to turn off E_NOTICE in this case.

Try using: 

if (isset($_COOKIE['NAME'])){
  echo "Cookie Is Set";
  // Continue cookie validation without the echo.
}

Because you currently are referring to the global $_COOKIE and not the individual key
