This the the format of cookie creation
这是 cookie 创建的格式
Syntax
句法
setcookie(name, value, expire, path, domain, secure, httponly);
so first variable is you cookie name
所以第一个变量是你的 cookie 名称
you can read this by using
你可以通过使用阅读这个
$_COOKIE['YOUR COOKIE NAME'];

Function session_name will give you hash which atucally is you session identifier. It seems like you want to get USERNAME stored in session, don't you? In that case you should use $_SESSION array.
函数 session_name 会给你哈希，这实际上是你的会话标识符。您似乎想将 USERNAME 存储在会话中，不是吗？在这种情况下，您应该使用 $_SESSION 数组。
Code example:
代码示例：
setcookie($_SESSION['USERNAME'],'HAMZA',1,
isset($params['path']),
isset($params['domain']),
isset($params['secure']),
isset($params['httponly']));
And you can get it like this:
你可以这样得到它：
$myCookie = $_COOKIE[$_SESSION['USERNAME']];
But from your second code it's not quite clear what you want to get. If you want to ask for $_COOKIE['USERNAME'] and get 'HAMZA' then you should set it like this:
但是从你的第二个代码来看，你想得到什么还不是很清楚。如果你想询问 $_COOKIE['USERNAME'] 并得到 'HAMZA' 那么你应该这样设置：
setcookie('USERNAME','HAMZA',1,
isset($params['path']),
isset($params['domain']),
isset($params['secure']),
isset($params['httponly']));
And when you retrieve it $NAME=='USERNAME' makes no sense, because it will be like $NAME=='HAMZA':
当你检索它时 $NAME=='USERNAME' 没有意义，因为它会像 $NAME=='HAMZA'：
$NAME=$_COOKIE['USERNAME'];
echo $_COOKIE['USERNAME'];
if(isset($NAME))
{
if($NAME=='HAMZA')
{
echo "success";
}
else
{
echo "error";
}
}
