Note Submitter: keuleu at hotmail dot com ---- The manual says somewhere above: "It is possible to access the overrided method or members by referencing them with parent::" I don't exactly know what it means by members, but if I'm not mistaking member is another term to designate variables or objects defined as properties of a class. I just would like to point out that although it is clearly possible to access parent *methods* like described (numerous examples on the internet), I have tried unsuccessfully to reference, overrided or not, parent *members* (protected or public) with the 'parent' keyword, nor was I able to find a well documented explanation on how to do so. Nowhere in the manual does it specifically tell you how to explicitly access parent variables. The only way I know is to use the traditional $this (which is not an explicit parent reference). The following example to illustrate: <?php class A{ public $x; function __construct(){ $this->x=33; } } class B extends A { function __construct(){ parent::__construct(); // works fine echo parent::$x; //this would have been explicit but it doesn't work echo $this->x; //implicitly accessing the same parent member will work fine } } $b = new B(); # Fatal error: Access to undeclared static property: A::$x on line 15 ?>
