This is apparently resolved in 4.2.2. However, the layout of the
return array from read_exif_data has significantly changed, so I'm
going to have to rewrite my code. In particular, there is no array
element named 'Comments' which was present in 4.1.2 (and I can find no
mention of this change in the ChangeLog or a footnote in the current
online documentation).
In fact, the additional parameters do not even work in PHP < 4.2. So
you have to code
$exif = @read_exif_data ($image, 0, true);
if (!isset($exif) || empty($exif)) {
// Fall back to PHP 4.1 read_exif_data()
$exif = read_exif_data ($image);
...
}
Someplace, a footnote to this effect would be nice. Should I open a
documentation bug?

I should have posted a small test sample. I'm putting one up on my web
site at http://www.astrofoto.org/people/roland/bug.php. The image
being probed can be loaded from the URL

I have a JPEG (*not* from a digital camera) to which I have added a
comment block using wrjpegcom. rdjepgcom confirms that the comment is
correct in the file. The length of the comment is about 345
characters.
When I read the comment back from PHP using read_exif_data, the length
is truncated at 198 characters. Note that JPEG comment blocks can be
up to 64k(!). The comment in question is all text, no ASCII nulls, so
I'm assuming this truncation is happening inside PHP.
