note 118054 added to language.oop5.abstract

The self keyword in an abstract class will refer to the abstract class itself, not the extending class no matter what. For instance the following code looks really pretty, yet results in a Fatal error (Cannot instantiate abstract class Basic). <?php abstract class Basic { public static function doWork() { return (new self())->work(); } abstract protected function work(); } class Keeks extends Basic { protected function work() { return 'Keeks'; } } echo Keeks::doWork(); ?> ---- Server IP: 72.52.91.14 Probable Submitter: 2001:7d0:88d9:2d01:a1d9:1e99:45e7:adb8 ---- Manual Page -- http://php.net/manual/en/language.oop5.abstract.php Edit -- https://master.php.net/note/edit/118054 Del: integrated -- https://master.php.net/note/delete/118054/integrated Del: useless -- https://master.php.net/note/delete/118054/useless Del: bad code -- https://master.php.net/note/delete/118054/bad+code Del: spam -- https://master.php.net/note/delete/118054/spam Del: non-english -- https://master.php.net/note/delete/118054/non-english Del: in docs -- https://master.php.net/note/delete/118054/in+docs Del: other reasons-- https://master.php.net/note/delete/118054 Reject -- https://master.php.net/note/reject/118054 Search -- https://master.php.net/manage/user-notes.php
