> 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 the SetCookie() function must be called before any
output is sent to the browser. This is the same restriction as
for the <A
HREF="function.header.html"
><B
CLASS="FUNCTION"
>Header()</B
></A
> function.
</P
><P
> Any cookies sent to you from the client will automatically be
turned into a PHP variable just like GET and POST method data. If
you wish to assign multiple values to a single cookie, just add
<I
CLASS="EMPHASIS"
>[]</I
> to the cookie name. For more details see
the <A
HREF="function.setcookie.html"
><B
CLASS="FUNCTION"
>setcookie()</B
></A
> function.
