What about stripping everything before, after, and including the
anglebrackets?  Then filling in the full name from the fullname (the FN
from the vcard?).

On other fronts, I checked fgetcsv - it's got the same problem as fgets.
It doesn't recognize end-of-lines that aren't LF.  CR is right out, and
CR/LF sticks a hidden CR in the entry.  It's been reported as a bug.
If / when the php folks address that, this can probably be made a lot
easier.
