note 112040 added to function.ctype-digit

Interesting to note that you must pass a STRING to this function, other values won't be typecasted (I figured it would even though above explicitly says string $text). I.E. <?PHP $val = 42; //Answer to life $x = ctype_digit($val); ?> Will return false, even though, when typecasted to string, it would be true. <?PHP $val = '42'; $x = ctype_digit($val); ?> Returns True. Could do this too: <?PHP $val = 42; $x = ctype_digit((string) $val); ?> Which will also return true, as it should. ---- Server IP: 64.71.164.2 Probable Submitter: 208.95.30.82 ---- Manual Page -- http://php.net/manual/en/function.ctype-digit.php Edit -- https://master.php.net/note/edit/112040 Del: integrated -- https://master.php.net/note/delete/112040/integrated Del: useless -- https://master.php.net/note/delete/112040/useless Del: bad code -- https://master.php.net/note/delete/112040/bad+code Del: spam -- https://master.php.net/note/delete/112040/spam Del: non-english -- https://master.php.net/note/delete/112040/non-english Del: in docs -- https://master.php.net/note/delete/112040/in+docs Del: other reasons-- https://master.php.net/note/delete/112040 Reject -- https://master.php.net/note/reject/112040 Search -- https://master.php.net/manage/user-notes.php
