1.2.411. Empty Classes¶
Classes that do no define anything at all : no property, method nor constant. This is possibly dead code.
Empty classes are sometimes used to group classes; an interface may be used here for the same purpose, without inserting an extra level in the class hierarchy. Classes that are directly derived from an exception are omitted.
<?php
//Empty class
class foo extends bar {}
//Not an empty class
class foo2 extends bar {
const FOO = 2;
}
//Not an empty class, as derived from Exception
class barException extends \Exception {}
?>
