New Comment:
This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.
Thank you for the report, and for helping us make our documentation
better.
According to beginning of CType chapter, small numbers are compared
differently. Equivalent part removed.

Documentation shouldn't say it's equivalent to regex matching when it
really isn't..docs need update, the function is fine as is.

Description:
------------
ctype_alnum returns false if you pass it an integer (ie 7). I know the
docs say that it should receive a string, as all ctype_* functions
should, but I believe it's pointless to have to do a ctype_alnum( '' .
$var ) at every call just to be sure. Also, the docs say that the
function is equivalent to preg_match('/^[a-z0-9]+$/iD', $text) and
matching 7 against that expression will work.
Reproduce code:
---------------
var_dump( ctype_alnum( 7 ) );
Expected result:
----------------
bool(true)
Actual result:
--------------
bool(false)
