note 96392 added to function.is-string

It took me a second to realize what was happening. When checking is_string() on an empty string, it fails. ie: function fetchType($var) { # Setup commonly used types (PHP.net warns against using gettype()) switch ($var) { case is_string($var): $type='string'; break; case is_array($var): $type='array'; break; case is_null($var): $type='NULL'; break; case is_bool($var): $type='boolean'; break; case is_int($var): $type='integer'; break; case is_float($var): // $type='float'; $type='double'; break; case is_object($var): $type='object'; break; case is_resource($var): $type='resource'; break; default: $type='unknown type'; break; } return $type; } echo fetchType(''); will output: array. ---- Server IP: 69.147.83.197 Probable Submitter: 63.103.168.2 ---- Manual Page -- http://www.php.net/manual/en/function.is-string.php Edit -- https://master.php.net/note/edit/96392 Del: integrated -- https://master.php.net/note/delete/96392/integrated Del: useless -- https://master.php.net/note/delete/96392/useless Del: bad code -- https://master.php.net/note/delete/96392/bad+code Del: spam -- https://master.php.net/note/delete/96392/spam Del: non-english -- https://master.php.net/note/delete/96392/non-english Del: in docs -- https://master.php.net/note/delete/96392/in+docs Del: other reasons-- https://master.php.net/note/delete/96392 Reject -- https://master.php.net/note/reject/96392 Search -- https://master.php.net/manage/user-notes.php
