note 66469 added to function.ctype-digit

Note that cytype_digit("") returns TRUE. This becomes clear if you read the definition closely -- anything is true about "all characters" in the empty string, since there is no character about which it could be false. But it isn't all that obvious. ---- Server IP: 66.163.161.117 Probable Submitter: 84.130.37.17 (proxied: 172.26.28.130, 172.26.20.2) ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.ctype-digit.php Edit -- http://master.php.net/note/edit/66469 Del: integrated -- http://master.php.net/note/delete/66469/integrated Del: useless -- http://master.php.net/note/delete/66469/useless Del: bad code -- http://master.php.net/note/delete/66469/bad+code Del: spam -- http://master.php.net/note/delete/66469/spam Del: non-english -- http://master.php.net/note/delete/66469/non-english Del: in docs -- http://master.php.net/note/delete/66469/in+docs Del: other reasons-- http://master.php.net/note/delete/66469 Reject -- http://master.php.net/note/reject/66469 Search -- http://master.php.net/manage/user-notes.php
