><P
>&#13;   PHP transparently supports HTTP cookies.  Cookies are a mechanism
   for storing data in the remote browser and thus tracking
   or identifying return users.  You can set cookies using the
   <A
HREF="function.setcookie.html"
><B
CLASS="function"
>setcookie()</B
></A
> function.  Cookies are part of the
   HTTP header, so <A
HREF="function.setcookie.html"
><B
CLASS="function"
>setcookie()</B
></A
> must be called before
   any output is sent to the browser.  This is the same limitation that
   <A
HREF="function.header.html"
><B
CLASS="function"
>header()</B
></A
> has. You can use the <A
HREF="ref.outcontrol.html"
>output buffering functions</A
> to delay the
   script output until you have decided whether or not to set any cookies or
   send any headers.
  </P
><P
>&#13;   Any cookies sent to you from the client will automatically be turned into a
   PHP variable just like GET and POST method data, depending on the
   <TT
CLASS="literal"
>register_globals</TT
> and <TT
CLASS="literal"
>variables_order</TT
>
   configuration variables.  If you wish to assign multiple values to a single
   cookie, just add <SPAN
CLASS="emphasis"
><I
CLASS="emphasis"
>[]</I
></SPAN
> to the cookie name.
  </P
><P
>&#13;   In PHP 4.1.0 and later, the <TT
CLASS="literal"
>$_COOKIE</TT
> auto-global
   array will always be set with any cookies sent from the client.
   <TT
CLASS="literal"
>$HTTP_COOKIE_VARS</TT
> is also set in earlier versions of PHP
   when the <TT
CLASS="literal"
>track_vars</TT
> configuration variable is set.
  </P

   <A

><B

>setcookie()</B
