httpOnly cookie flag support in PHP 5.2

http://ilia.ws/archives/121-httpOnly-cookie-flag-support-in-PHP-5.2.html
Thanks to a patch from Scott
MacVicar that I've just applied to CVS, PHP 5.2 will have support for
httpOnly cookie flag. This neat little feature allows you to mark a
newly created cookie as HTTP only, another words inaccessible to
browser based scripting languages such as JavaScript. This means it
would become far more difficult, if not impossible to steal a user's
cookie based session by injecting JavaScript into a page and then using
to read cookies.
This flag can be toggled by passing TRUE as the 7th parameter to the
setcookie() and the setrawcookie() functions respectively. Ex:
PHP:
<?
php
setcookie
(
"abc"
, 
"test"
, 
NULL
, 
NULL
, 
NULL
, 
NULL
, 
TRUE
); 
setrawcookie
(
"abc"
, 
"test"
, 
NULL
, 
NULL
, 
NULL
, 
NULL
, 
TRUE
); 
?>
The support of the httpOnly flag extends to the session extension as
well, where it can be enabled by setting the session.cookie_httponly
INI setting to 1. Or passing TRUE as the 5th parameter to the
session_set_cookie_params() function.
PHP:
<?
php
ini_set
(
"session.cookie_httponly"
, 
1
);
// or
session_set_cookie_params
(
0
, 
NULL
, 
NULL
, 
NULL
, 
TRUE
);
?>
Unfortunately, at this time according to my tests no other browser has
adopted this rather handy feature, but with the continual increase of
XSS attacks, I am sure they'll adopt this concept soon.
For people using PHP 4 and PHP 5.1 you can add this flag yourself by
sending cookies manually via the header function and prefixing the
;httpOnly flag to the cookie as shown in the example below:
PHP:
<?
php
header
(
"Set-Cookie: hidden=value; httpOnly"
);
?>
