Ok, Thise I do understand.
I still have some questions.
Is it possible to set a cookie without a timestamp? (o it's always on the
computer. until the user ....)
When I the cookie is already setted, I like to use it. When I use it, i have
to set it. After setcookie, I use the last cookie setted file, but als I
overwrite that one with the new one. So the next time I use the cookie, I
have the settings of the last time.
Perhaps I have a answere by myself. Should it work?
I can checkabout the settings:
is setted? Y/N
Y? check language (is set in a cookie)
- NL= start a new PHP file with a setcookie with the settings for
language=NL.
- EN= ... etc.
N? give chooice and setcookie
But how do I do this?
