php7中如何设置COOKIE和销毁COOKIE

1，如何设置COOKIE

setcookie ( string $name [, string $value = "" [, int $expire = 0 [, string $path = "" [, string $domain = "96net.com.cn" [, bool $secure = false [, bool $httponly = false ]]]]]] ) : bool

setrawcookie() 再设置值时候原样输出

2，销毁COOKIE

setcookie("TestCookie", $value, time()-3600);

3，获取COOKIE值

echo $_COOKIE["TestCookie"];
