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.

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.
