note 92204 added to language.oop5.basic

For those of us who are new to inheritance, private functions are not visible in an inherited class. Consider: <?php class A { protected function func1() { echo("I'm func1 in A!<br/>"); } private function func2() { echo("I'm func2 in A!<br/>"); } } class B extends A { public function func3() { echo("I'm func3 in B!<br/>"); $this->func1(); $this->func2(); // Call to private function from extended class results in a fatal error } } $b = new B; $b->func3(); // Ends in a fatal error // OR $b->func1(); // Call to protected function from outside world results in a fatal error ?> If you want a function to be accessible in class B but not to the outside world, it must be declared as protected. ---- Server IP: 209.41.74.194 Probable Submitter: 66.78.98.194 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.basic.php Edit -- https://master.php.net/note/edit/92204 Del: integrated -- https://master.php.net/note/delete/92204/integrated Del: useless -- https://master.php.net/note/delete/92204/useless Del: bad code -- https://master.php.net/note/delete/92204/bad+code Del: spam -- https://master.php.net/note/delete/92204/spam Del: non-english -- https://master.php.net/note/delete/92204/non-english Del: in docs -- https://master.php.net/note/delete/92204/in+docs Del: other reasons-- https://master.php.net/note/delete/92204 Reject -- https://master.php.net/note/reject/92204 Search -- https://master.php.net/manage/user-notes.php
