Huh?  It did exactly what you asked to do.  You had three spaces, and you
requested that two be replaced by one.  So, you went from three spaces to two
spaces, as two of the three were combined into one.  I don't understand why
you expected to end up with one space.  Can you elaborate please?

Thanks,
Chris

[PHP] Re: Download the whole directory

[Christian Kuhtz]

No.  You cannot initiate multiple transactions that way (at least not without
considerable glue outside of PHP, such as JavaScript etc to cause the browser
to initiate multiple transactions; but it cannot be done directly from the
server side as the client only asked for one file).  

You could zip or tar the directory up and send it to the client in one file,
one transaction.

Overriding an existing cookie with setcookie()and 1 sec expiry should do the
trick.
