<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 HTTP 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 you from the client will automatically be turned into a
|
||||
PHP variable just like GET and POST method data, depending on the
|
||||
<literal>register_globals</literal> and <literal>variables_order</literal>
|
||||
configuration variables. If you wish to assign multiple values to a single
|
||||
cookie, just add <literal>[]</literal> to the cookie name.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
In PHP 4.1.0 and later, the <varname>$_COOKIE</varname> auto-global array
|
||||
will always be set with any cookies sent from the client.
|
||||
<varname>$HTTP_COOKIE_VARS</varname> is also set in earlier versions of PHP
|
||||
when the <literal>track_vars</literal> configuration variable is set. (This
|
||||
setting is always on since PHP 4.0.3.)
