 is_numeric() is a standard function for php version 4 and 5, while
 ctype_digit() is avaliable only in the "ctype" extension, which may have
 no support at all. In WordPress they refused ctype starting from the
 version 2.5.1, see for reference
 http://core.trac.wordpress.org/search?q=ctype_digit

 And now if the "ctype" extension is missing on the server, a WP user can't
 upload media in wordPress through the administration panel. Perhaps you
 should add this enhancement to 2.9.1 or 2.9.2 milestone.

 For those user, that already have the same problem, I propose use the
 following snippet in the template functions.php

 {{{
 if(!finction_exists('ctype_digit')) {
  function ctype_digit( $num ) { return is_numeric( $num ); }
 }
 }}}
