New Comment:
an empty string is a string ;)
the documentation says:
" When called with a string argument they will check every character in
the string and will only return TRUE if every character in the string
matches the requested criteria. "
can't see the contradiction here as in an empty string every of the 0
charactetrs matches the criteriy ...
will add a note about that in the documentation,
but the behaviour will not change for backwards
compatibility reasons

The PHP ctype functions return TRUE when passed a zero
length string. This is incorrect behavior; see the
documentation for the contradiction. This is not an issue
with the C ctype functions, since they deal with
characters, which cannot be zero-length.
The following patch corrects this behavior
--- ctype.c 2002-07-18 23:58:02.000000000 -0500
+++ ctype_fixed.c 2002-07-18 23:57:48.000000000
