[mohamad_1978]

hi guys
i have problim is cookies .. im working is small program the i add qustions for the users with (yes or no) answers many qustions in the database the users come and answer and the can only answer one (useing cookies)
i made the normal way

setcookie ("do$id",1,"$expires");

where the $id is = the id of the qustion the user answer and $expires is for the expires time

it iw work fine with the first 11 qustions but when i do the number 12 it delete number 1 cookie and when i do number 13 it delete number 2 and so on

i think there is max number of cookies ? maybe that why

so i think to put all of the qustion's number in one cookie useing array

i never work with it so i do this as test

setcookie ("do[$id]",1,"$expires");

Use this to name instead

setcookie("do".$id,1,$expire);

Try using serialize() then you can put an array inside a cookie. To update it use unserialize() and the again serialize() and update cookie.
