    $HTTP_COOKIE_VARS [deprecated]

    $_COOKIE -- $HTTP_COOKIE_VARS [deprecated] — HTTP Cookies

    설명

    An associative array of variables passed to the current script via HTTP Cookies.

    $HTTP_COOKIE_VARS contains the same initial information, but is not a superglobal. (Note that $HTTP_COOKIE_VARS and $_COOKIE are different variables and that PHP handles them as such)

    Dots (.) and spaces ( ) in cookie names are being replaced with underscores (_).

    Cookies with the same name the first cookie is used. Clients will send cookies with longer path before cookies with shorter path. This comes from RFC 6265 which says "Cookies with longer paths are listed before cookies with shorter paths.". So you get the best matching cookie for your current request.
