Comments:
indeed i have missed one of the points - the fact that when passing data in the array form, all the
values combine in a single array. further testing showed that the cookies also appear in
HTTP_GET_VARS. i am sure that if there is a post to an url with a get var and some cookies (all
varnames in array form) HTTP_*_ARRAY will contain all the values.
this issue is a serious concern about the --enable-track-vars code. it must be resolved by
overwriting the whole arrays, not adding data to them in order to be consistent
e.g.
get var: myarr[one]=1
post var: myarr[two]=2
cookie var: myarr[three]=3
gpc order is GPC
the global array $myarr has only the 'one' key
the HTTP_*_VARS have only the proper arrays

think about cookies the same way as GET data or POST data - they are at the same level and can be
spoofed very easy with a cURL client for example. one can tell his client what cookie with what
value to pass for a given request
the issue here is not security but programmers comfort. but when one uses the short representations
of variables she must be aware of the GPC order setting.
i think this is the same like overriding a post variable with a get one.
do you think this bug shall be closed?

<?
setCookie('cookie[one]','one');
setCookie('cookie[two]','two');
print_r($HTTP_COOKIE_VARS);
?>
If you access this page with the command line arguement
?cookie[three]=three
print_r will show cookie[three] in $HTTP_COOKIE_VARS.
Just a bit of incongrous material, but for some sites could cause problems if cookies are spoofed
thusly.
