Bug description: Magic __parent property (or method)
Description:
------------
When writing code with complex object structures I often need a reference
to the parent object. Let's say we have an object "parent" that has a
property which is an object "child":
class parentClass {
var $child;
var $dummyVar;
function __construct() {
$this->child = new childClass($this);
$this->dummyVar = 'hello';
}
}
class childClass {
var $parent;
function __construct($parent) {
$this->parent = $parent;
echo $this->parent->dummyVar;
}
}
$example = new parentClass;
// prints: hello
I very often need to create my code like this because I very often need to
be able to have a reference to the parent object of an object.
Shouldn't PHP have such a reference by default? There could always be a
Magic reference like:
$myParent = $this->__parent;
Or maybe a Magic method:
$myParent = $this->__parent();
This would then always return the parent object or eventually reach the
main script scope.
