It's not clear to me what you want - create a text file on the server, or
create a CSV file for download on the fly...

As fopen() tries to create a local file, it seems you (or better, the uid
owning the web server process) do not have write permission to where you
want to create the file. Your PHP scripts run with the user-id of the web
server, which may be www-data, nobody, wwwrun or whatever. You may have to
ask the server admin to give that process write permission in your diectory.

On the other side it may be better and easier to create a csv file on the
fly. Create a page, say csv-export.php, and link to it using a
href="csv-export.php/export.csv". This way the user's browser is tricked
that the link points to a CSV file, if it does not honor the content-type it
sends (see below).

In csv-export.php you do
Header ("Content-type: text/csv");

... [insert code here to generate csv data. Just echo() it.] ...

And one other thing that caused me headache for at least 4 hours: Your CSV
File MUST NOT begin with "ID". Excel (at least '97 and 2000) tries to open
that file with the SYLK import filter, which always fails. Put a space in
front of ID, and you're safe.
