Note Submitter: Compvir ---- Dear son9ne dot junk at gmail dot com. The thing is that it is your function fetchType is working wrong. It also will say that the following variables are strings: false, 0, null - though they are bool, integer and null respectfully. The mistake is that you compares $var with the result of is_<type>($var). If $var is some type then is_<type>($var) will return true and thereafter you should make the following code to receive correct answer: <?php function fetchType($var) { # Setup commonly used types (PHP.net warns against using gettype()) switch (true) { case is_string($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(''); ?>
