note 118717 added to language.oop5.abstract

The abstract keyword cannot be used to dictate properties or class constants that a derivative class must set/define. Instead, those required properties or constants can be included in the abstract class with the expectation that they will be overridden in derivative classes, which at least ensures that the desired property/constant is set/defined. ---- Server IP: 72.52.91.14 Probable Submitter: 72.195.139.26 ---- Manual Page -- http://php.net/manual/en/language.oop5.abstract.php Edit -- https://master.php.net/note/edit/118717 Del: integrated -- https://master.php.net/note/delete/118717/integrated Del: useless -- https://master.php.net/note/delete/118717/useless Del: bad code -- https://master.php.net/note/delete/118717/bad+code Del: spam -- https://master.php.net/note/delete/118717/spam Del: non-english -- https://master.php.net/note/delete/118717/non-english Del: in docs -- https://master.php.net/note/delete/118717/in+docs Del: other reasons-- https://master.php.net/note/delete/118717 Reject -- https://master.php.net/note/reject/118717 Search -- https://master.php.net/manage/user-notes.php
