note 118098 added to function.ctype-digit

I just wanted to clarify a flaw in the function is_digit() suggested by "info at directwebsolutions dot nl " .. It returns true in case of negative integers and false in case of strings that contain negative integers . example: is_digit(-10); // returns ture is_digit('-10'); // returns false ---- Server IP: 72.52.91.14 Probable Submitter: 197.160.96.48 ---- Manual Page -- http://php.net/manual/en/function.ctype-digit.php Edit -- https://master.php.net/note/edit/118098 Del: integrated -- https://master.php.net/note/delete/118098/integrated Del: useless -- https://master.php.net/note/delete/118098/useless Del: bad code -- https://master.php.net/note/delete/118098/bad+code Del: spam -- https://master.php.net/note/delete/118098/spam Del: non-english -- https://master.php.net/note/delete/118098/non-english Del: in docs -- https://master.php.net/note/delete/118098/in+docs Del: other reasons-- https://master.php.net/note/delete/118098 Reject -- https://master.php.net/note/reject/118098 Search -- https://master.php.net/manage/user-notes.php
