If you have access to read the files and the comments are clearly
delineated, then its shouldn't be hard to open each file and then pull
out the contents with regex or str parsing.
You might want to store the data somehow, so that in the future you
only have to read in the changed files.

The comments on a windows file (on the NTFS file system) are held in
Alternative Datastreams
(http://en.wikipedia.org/wiki/Fork_(filesystem)). As far as I know PHP
cannot natively access them, though externals tools exist ...

Or are you talking about a file whose content is a list of comments?

If the files exist on a Linux server, then you're out of luck, because
as Richard said, this information is kept in the alternate data streams,
which is part of the NTFS filesystem (and I don't know anyone crazy
enough to install Linux onto an NTFS formatted partition!)
What you could do is store the filenames in a database, and use a second
table for the comments, attributing them to a file. This would lend
itself well for web-based use, but will cause problems if you move the
files (as the database would lose track of them)
Some file formats are built to allow extra data though. For example,
images have EXIF data, for which there are ways to read (and write
afaik) within PHP. Most audio formats have this, and I would assume
video formats too. You'll probably find most file formats have something
available for this, but the deployment will vary from file type to file
type.
Thanks,
Ash

Thanks for the input, all. I decided to write a quick and easy =
Web-based file manager using my database to store the comments, as =
suggested.
Thanks!
