From: Contact at LinuxIntro dot com Operating system: Fedora PHP version: 5.2.6 PHP Bug Type: MySQLi related Bug description: no access to error when extended class
Description: ------------ I know that this is a 'no no', but i feel that the bug here was not bogus: http://bugs.php.net/bug.php?id=37711 I disagree with the response. $this is used in the current class, whereas parent:: is used to access properties and methods of the parent class. errno and error are properties of the parent class, NOT of $this class. Using $this to access the property of parent:: is not inheritance, it is more closely related to symbiosis or polymorphism, or something. And besides, how is parent:: automatically giving $this new properties called errno and error? Shouldn't that only be done via a set/get type function? EX: function GetErrno(){ $this->errno=parent::errno; } function GetError(){ $this->error=parent::error; } The fact that this is automatically available in the scope of $this is NOT inheritance, imho, it is a BUG.
