cookies are variables stored in user pc (client) by server.
When client load the page first send to server the variable so
the server knows it.
This is how work cookies.
There are some data that make a cookie:
name for referring it
value ... of course!
the time of live of the valiable
the scope (visibility) of variable.
Think to cookie as an array of these value (name, value, time, scope...)
in client.
Said that there are some function:
setcookie is used to write the value toclient.
$_COOKIES[name_of_variable] for reading it
Probabli the difficult you find in this script i due to
the time of processing it:
The first time you call it just write th cookie.
from the second time the cookie is setted!
