note 96392 deleted from function.is-string by danbrown

Note Submitter: son9ne dot junk at gmail dot com ---- It took me a second to realize what was happening. When checking is_string() on an empty string, it fails. ie: <?php 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.
