note 60382 added to language.oop5.visibility

Beware: Visibility works on a per-class-base and does not prevent instances of the same class accessing each others properties! <?php class Foo { private $bar; public function debugBar(Foo $object) { // this does NOT violate visibility although $bar is private echo $object->bar, "\n"; } public function setBar($value) { // Neccessary method, for $bar is invisible outside the class $this->bar = $value; } public function setForeignBar(Foo $object, $value) { // this does NOT violate visibility! $object->bar = $value; } } $a = new Foo(); $b = new Foo(); $a->setBar(1); $b->setBar(2); $a->debugBar($b); // 2 $b->debugBar($a); // 1 $a->setForeignBar($b, 3); $b->setForeignBar($a, 4); $a->debugBar($b); // 3 $b->debugBar($a); // 4 ?> ---- Manual Page -- http://www.php.net/manual/en/language.oop5.visibility.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60382 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60382&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60382&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60382&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60382&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60382&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60382&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60382&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60382&report=yes Search -- http://master.php.net/manage/user-notes.php
