delete array cookie

[searain]

Say I have an array cookie MyArrayCookie[].

Now I want to delete this cookie, can I use the statment

setcookie("MyArrayCookie");

Or should I use for loop to delete the cookie by delete every array element one by one?

for ($index=0; $index<count($MyArrayCookie); $index++)
{
setcookie("MyArrayCookie[$index]");
}

Thanks!

for a domain the number of cookies is limited. if you want to keep in cookie an array (and attention - cookie is limited by size too). you should use:
$a=myarray

setcookie('cookievar',serialize($a))

and when u get your array from cookie: $a=unserialize($_COOKIE["cookievar"])

and when you delete the cookie you have to delete one cookie.

i think it an idea.

if I use this

for ($index=0; $index<=21; $index++)
{
setcookie("number[$index]", $index);
}

Am I using one cookie or 21 cookies?

to delete a cookie all you do is reset it so that it expired some time in the past.

ie: you set it to expire in hte year 3003
the person logs out, so you reset it having it expire in 1001
