note 78136 added to language.oop.constructor

I found a reasonably neat way in PHP4 to solve the problem of calling superclass constructors without needing to embed knowledge of the entire class hierarchy into each class: <?php class A { function A () { $this->constructor(); } function constructor () { ....this is the "A" constructor body.... } } class B extends A { function B () { $this->constructor(); } function constructor() { /* Call superclass constructor */ parent::constructor(); ....this is the "B" constructor body.... } } ?> Note that the fact that class B inherits from class A is encoded in precisely one place: the "extends" clause, and is not duplicated within the class B constructor body, as would be the case had we used something more traditional: <?php class B extends A { function B() { $this->A(); /* "extends A" information would be duplicated here */ ....this is the "B" constructor body.... } } ?> ---- Server IP: 87.124.64.96 Probable Submitter: 81.107.32.114 ---- Manual Page -- http://www.php.net/manual/en/language.oop.constructor.php Edit -- https://master.php.net/note/edit/78136 Del: integrated -- https://master.php.net/note/delete/78136/integrated Del: useless -- https://master.php.net/note/delete/78136/useless Del: bad code -- https://master.php.net/note/delete/78136/bad+code Del: spam -- https://master.php.net/note/delete/78136/spam Del: non-english -- https://master.php.net/note/delete/78136/non-english Del: in docs -- https://master.php.net/note/delete/78136/in+docs Del: other reasons-- https://master.php.net/note/delete/78136 Reject -- https://master.php.net/note/reject/78136 Search -- https://master.php.net/manage/user-notes.php
