I'm converting some old PHP 4.x code for PHP 5.3. I've come across the following, and I'm not sure what it does.
$variable =& new ClassName();
What is the difference between that, and:
$variable = new ClassName();

Assuming you have a constant defined in a class:
class Foo {
const ERR_SOME_CONST = 6001;
function bar() {
$x = 6001;
// need to get 'ERR_SOME_CONST'
}
}
Is it possible with PHP?

String className = "com.package.MyClass";
Class c = Class.forName(className);
Object obj = c.newInstance();
How I can dynamically convert that obj to MyClass object? I can't write this way:

Hi. I am trying to make a class helper for the Color class in C#. I am a Delphi programmer and as far as I know, class helpers allow you to expand base classes so when you create an instance of the base class, you have access not only to the base methods, but also to all those defined in the helper class.
Is it possible to achieve a simi...

Suppose that I have two data types Foo and Bar. Foo has fields x and y. Bar has fields x and z. I want to be able to write a function that takes either a Foo or a Bar as a parameter, extracts the x value, performs some calculation on it, and then returns a new Foo or Bar with the x value set accordingly.
Here is one approach:

I access the camera via UIImagePickerController, and when I set the delegate to self, I can use the delegate methods. However, for what I have planned I need to have the delegate methods in another class, but whenever I try to do that, it will dismiss the the picker whenever I take a picture.
When I do this, it works:

Hi. I have a class with a constant defined for it. I then have a class method defined that accesses that class constant. This works fine. An example:

def shout_my_constant
puts Const.upcase
end

This happens to me a lot and I've yet to find a good solution. Say you have two classes, Tree (com.company.Tree) and Fruit (com.company.Fruit). On the stage in Flash, the Tree has an instance of Fruit (class=fruit1, base class=com.company.Fruit), and it's instance name is fruit. Everything is fine, until you duplicate the tree and fruit ...
