  <title>Cookies</title>

  <para>
   PHP transparently supports <acronym>HTTP</acronym> 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 <function>setcookie</function> or
   <function>setrawcookie</function>
   function.  Cookies are part of the <acronym>HTTP</acronym> header, so
   <function>setcookie</function> must be called before any output is sent to
   the browser.  This is the same limitation that <function>header</function>
   has. You can use the <link linkend="ref.outcontrol">output buffering
   functions</link> to delay the script output until you have decided whether
   or not to set any cookies or send any headers.
  </para>

  <para>
   Any cookies sent to server from the client will automatically be included into
   a <varname>$_COOKIE</varname> auto-global
   array if <link linkend="ini.variables-order">variables_order</link>
   contains "C". If you wish to assign multiple values to a single
   cookie, just add <literal>[]</literal> to the cookie name.
  </para>

  <para>
   For more details, including notes on browser bugs, see the
   <function>setcookie</function> and <function>setrawcookie</function>
   function.
