I've written a PHP program to "mirror" data on a local drive to a

Did you consider just using rsync?...
To examine the remote directories, I use ftp_rawlist() to get a
directory
listing which I parse. However, the file modification time does not
have a
year, and does not show the seconds. I get around this by "assuming"
the
year is the current one, and then compare the file times of the local
and
remote files ignoring local file seconds. If they are different, I use
ftp_mdtm() to get the real remote time, and then do my compare. This
slows
things down a bit, as I have to go to the FTP server one more time.
If the minutes are different, why would you bother to check the
seconds?...
Any thoughts on how to get around this?
Is there a way to get a better
directory listing?
I've seen some FTP servers that response to 'ls -als' with about what
you'd expect from the shell.
How they do it, I dunno, but I like it.
Second and more serious problem is that when I FTP the file to the
server,
the file mod time gets set to the current (file-creation) time. The
same
thing happens in a local-to-local file copy using copy(), but I can
use
touch() to update the mod time.
rsync would fix this.
You could also look at scp which allows you to specify that you want
to maintain file attributes.
Any thoughts on how I might get the remote FTP server to do the
equivalent
of touch()?
Actually, I should think you'd want to convince the server to "know"
when the file was REALLY created/modifed based on the local file, not
force the local file to look different just to accomodate the FTP
server.

I want you to buy a CD from some starving artist.
