note 80106 added to function.empty

Also, it doesn't appear to mention in the documentation, if a variable hasn't previously been declared, empty also returns true. E.g. var $bar; empty( $bar ); // declared variable returns true. empty( $foo ); // undeclared variable also returns true. The closest the documentation comes to saying this is: "var $var; (a variable declared, but without a value in a class)" which isn't really the same, as the variable doesn't necessarily have to be declared first. ---- Server IP: 87.124.64.96 Probable Submitter: 83.216.141.253 ---- Manual Page -- http://www.php.net/manual/en/function.empty.php Edit -- https://master.php.net/note/edit/80106 Del: integrated -- https://master.php.net/note/delete/80106/integrated Del: useless -- https://master.php.net/note/delete/80106/useless Del: bad code -- https://master.php.net/note/delete/80106/bad+code Del: spam -- https://master.php.net/note/delete/80106/spam Del: non-english -- https://master.php.net/note/delete/80106/non-english Del: in docs -- https://master.php.net/note/delete/80106/in+docs Del: other reasons-- https://master.php.net/note/delete/80106 Reject -- https://master.php.net/note/reject/80106 Search -- https://master.php.net/manage/user-notes.php
