note 97854 added to function.is-string

Re: When checking is_string() on an empty string, it fails. You don't use "switch" correctly. If $var is '' then will evaluate to "false" and is_string($var) will evaluate to "true" and is_array($var) will evaluate to "false". Basicaly you have: switch(''){ case true: $type='string'; break; case false: $type='array'; break; ... } In this case you can use a sequance like this: if( is_string($var) )return 'string'; if( is_array($var) )return 'array'; ... return 'unknown type'; or if( is_string($var) ) $type='string'; elseif( is_array($var) ) $type='array'; ... else $type='unknown type'; return $type; Sorry for my bad english. ---- Server IP: 69.147.83.197 Probable Submitter: 89.115.89.2 ---- Manual Page -- http://www.php.net/manual/en/function.is-string.php Edit -- https://master.php.net/note/edit/97854 Del: integrated -- https://master.php.net/note/delete/97854/integrated Del: useless -- https://master.php.net/note/delete/97854/useless Del: bad code -- https://master.php.net/note/delete/97854/bad+code Del: spam -- https://master.php.net/note/delete/97854/spam Del: non-english -- https://master.php.net/note/delete/97854/non-english Del: in docs -- https://master.php.net/note/delete/97854/in+docs Del: other reasons-- https://master.php.net/note/delete/97854 Reject -- https://master.php.net/note/reject/97854 Search -- https://master.php.net/manage/user-notes.php
