registerNodeClass is great for extending the various DOMNode-based DOM classes in PHP, but I need to go one level deeper. I've created an extDOMElement that extends DOMElement. This works great with registerNodeClass, but I would like to have something that works more like this: registerNodeClass("DOMElement->nodeName='XYZ'", 'extDOMXYZ...
Is it a bad practice to have a package with only one class in it? Would it make more sense just to move the single class to a util package that would contain other random useful classes? ...

Lets say I have this class (just as an example): internal class Packet { private readonly UInt32 _length; private readonly Byte _type; private readonly UInt32 _requestId; } There are many different types of packets each of which inherit from this class and each packet type can have any number of properties of varying typ...

If I have a class that includes a file with a constant like so: define("FOO", "bar"); Is there a way to make the class include the file with encapsulation so if I use the class somewhere that already has a FOO constant defined it won't break? ...
I have designed a hierarchy, every class has 2 readonly properties mapped to 2 private fields. Every class has a cosntructor that inherits the parent class one. The problem is that at every level of hierarchy the number of parameters increase of 2: TBaseClass.Create (par1, par2); TSubClass.Create(par1, par2, par3, par4); TSubSubClass....
Say I have a class like this: @interface MyAwesomeClass : NSObject { @private NSString *thing1; NSString *thing2; } @property (retain) NSString *thing1; @property (retain) NSString *thing2; @end @implementation MyAwesomeClass @synthesize thing1, thing1; @end When accessing thing1 and thing2 internally (i.e, within the impleme...

So, I'm having trouble with some php OO stuff. I think the code will explain it best: class foo { $someprop; public function __construct($id){ $this->populate($id); } private function populate($id){ global $db; // obviously not the call, but to illustrate the point: $items = $db->get_fro...
Don't get me wrong - OOP currently is the best thing to structure large code bases. But why do people try to stuff anything into an OO view? For example: each text book about OOP contains an "introducing example" that tries to express a small view of our real world in an OO inheritance and composition and aggregation construct. And - m...

In a few weeks, I will guide some of our trainees through a customer project, where they have to build a small web application in php. My idea is to setup a small MVC structure for them to learn oop and mvc and to assure code quality. How would you do this? We have no special requirements, just php and mysql. Would you use a template sys...

In C# using VS2005, if I have a variable of type Object, to which I assign a MyObjectType object by casting as follows: MyObjectType myObj = GetMyObject(); Object obj = (Object)myObj; Is there way to determine that obj is actually a MyObjectType and not just an Object? ...
Let's say that I have two classes A and B. class A { private: int value; public: A(int v) { value = v; } }; class B { private: A value; public: B() { // Here's my problem } } I guess it's something basic but I don't know how to ca...
I have a some type hierarchy: type A, type B contains field of type A array, type C contains field of type B... (added: I mean type structure, not classes!) I can't use classes by performance reason: type objects copying and creating more fast than the same for classes. But now I need substitute lowest type and than use both types, ol...
