Description:
------------
Hello everybody, I think, I found a bug
(I'm using latest versions: 4.3.10RC1 & PHP 5.0.2)

The FUNCTION ctype_alnum() must return FALSE in my case... but return TRUE.

I'm sorry for my english.

Reproduce code:
---------------
<?
if(ctype_alnum(""))
exit("ok");

else
exit("error")
?>

Expected result:
----------------
error

Actual result:
--------------
ok

This bug has been fixed in CVS.

Thank you for the report, and for helping us make PHP better.

This was fixed in PHP 5.1, it will not be fixed in earlier released due to change breaking backwards compatibility.
