I did try to find the answer to this before posting, so this isn't a
knee jerk reaction.
What I am trying to accomplish is to have a script that opens a
cookie, reads a value, and then use a switch/case to take action based
on that value in the cookie. I want to set the cookie manually, so I
don't need setcookie(). I see that in PHP it stores the cookie in
memory. Is there a way to have PHP just read a cookie from the desktop
machine? Does it have to set it first? Am I better off with Javascript
for this?
The situation is that we have 4 computers. We also have 4 different
types of specialty printers, each for a different function. We don't
know which computer will be hooked up to which printer, and they may
be switched out routinely. We are trying to develop a simple script
that reads the value of the cookie which tells it which printer to
print to and what to print. This way, we can easily switch computers
around as needed, and will only need to change the value in the cookie
to have it access the correct code so that it prints the correct
information in the correct format.

I hope i don't miss some point, but generally speaking:
1) On page #1 EITHER php during the page rendering OR client javascript
anytime, even later, SETS UP a cookie.
2) Person clicks a link submits a form to MOVE ON to page #2 on same domain.
3) On page #2 EITHER php OR client javascript READS that cookie and have
some fun with it (does it's thing).
Of course even both can set cookies and have fun together, but that' not the
point.
No comments on the final problem, but somehow i felt that this needed to be
written to clarify.

But of course it needs to be added that ajax, i believe, gives more
opportunities to play with cookies, since php calls are not restricted to
initial page rendering.

Not exactly.We will have a simple registration form that a customer
fills out at a kiosk. They click submit and the customer is done. From
there the registration info is sent to a PHP script which first opens
a cookie on the client computer and reads the value. Next, it runs
through a list of switch/case statements based on that value to
determine which printer the client computer is using and what format
it needs to print in (This is for remote printing, to one of four
possible printers). This way, when we move a computer to a different
printer, we just change the value in the cookie and it starts printing
correctly. (We are using a remote server for the data collection, and
local PC to print.)
Since each printer is different, the setcookie() method would not
work because it can only set one value across four machines (Unless we
did four different scripts, which would get confusing). We need to be
able to have four different values for the same cookie. We also need
to be able to manually change the value when the computer moves. Think
of a file that you create on four different computers. Each file has
the same name, but a different letter in it; A, B, C or D. The program
opens the file up on each computer, reads in A, B, C or D. Then it
takes action on whether the file contained A, B, C or D. That is what
we are trying to accomplish with cookies. We don't want to create the
file each time the program runs, because the file is already there.
So - if I understand right- situation is this:
- There are four printers.
- Those machines that are somewhere close to printer x, should be able to
communicate to php (when it's rendering the page) that all php-made-printing
from this page request goes to printer x, since it is server PHP that
prints, not the local machine.
- Your personnel - but nobody else - can move any computer to a new
location, that is, closer to another printer than before.
- That's why you need to be able to change easily that location info, that
is again permanent, until you decide move the computer again.
Question is then also, is the cookie right or only way to accomplish this?
Usually kiosks use kiosk mode of the browser. You can start the browser
with http://example.com?printer=a or http://example.com?printer=b etc.,
after that it would be php session variable that can hold the info on the
printer. Or cookie. You could have four shortcut icons on the desktop to
make the starting easy. You could name them in descriptive way:
START-HERE-WHEN-UR-CLOSE-2-PRINTER-X
May it be my stupidity, if I misunderstood you. I hope you find the solution
anyway.

You can use a cookie for this. But here's a suggestion - have a
password-protected admin page which sets the cookie. When they move the
computer, they have to log into the admin page and tell it which printer
to use.
This then sets the cookie, which is now available for the rest of your
pages. Of course, you would want to ensure that cookies are not cleared
when the browser shuts down - at least not for your site.

I talked with my boss, and he is completely against the kiosk mode
(for whatever reason). Let's step back from the word cookie for a
minute.
We are going to have 4 "kiosk" style computers, each of which display
the same registration form on a remote server. As the customer fills
out the form, he may get redirected to other forms based on how he
answered (Multiple paths). The very last step for everyone, after
everything is filled out and the customer submits the form, we want to
have a small script on the server that accesses a file on the kiosk
computer. The script on the server will read the value and perform an
action based on that value.
Cookie is the word my boss threw out there. I don't see why it has to
be a cookie, if PHP can access a remote file on the "kiosk" machine
from the server. We don't want to pass the value with the URL, as he
would have to go back and change all the pages of the PHP form to
pickup the value and pass it along to the next page.

Can you imagine what fun the hackers would have if there were a way to

Okay, so we are going with cookies. The problem I have is that I don't
know how to make PHP just read a cookie. I understand how to set a
cookie, and it is stored in memory, which then can be used throughout
the form. I even know how to set a time limit on a cookie to make it
stay on the kiosk computer, but again, we don't want to create the
cookie.
The problem is that I don't want to set a cookie. I want to just read
one that I create manually. Obviously, setting a cookie through our
PHP form would only be able to set one value for all four machines,
yet we want to have 4 different values. Is there a way to just read a
cookie without setting it through PHP?
