Bug description:  ctype_digit returns 1 for an empty string

Description:
------------
ctype_digit returns 1 (TRUE) for an empty string (I do not mean a blank
character) however it must return false (NULL) because empty string means
there is no digit. 

Reproduce code:
---------------
$number="";
print ctype_digit($number)."*";
$number=" ";
print ctype_digit($number)."*";
$number="1";
print ctype_digit($number);

Expected result:
----------------
**1

Actual result:
--------------
1**1
