I’m fairly new to CodeIgniter and have a question. I’m a bit confused about Classes, Libraries and Objects. Does CodeIgniter replace the normal PHP way of usings objects i.e. $var = new car(); with libraries i.e. $this->load->library('some_library'); $this->some_library->some_function(); ? If both are valid, is there a difference? If s...

Hi, I'm a PHP developer trying to write some C++. I'm having trouble with assigning an object as an another object's property. In PHP, I'd write this: class A { public $b; } class B { } $a = new A; $a->b = new B; How do I do that in C++? I got this so far: class A { B b; public: void setB(&B); }; class B { }; void A:...
I'm embarking on a very big exercise to build a CMS in php. It's actually my attempt to learn PHP in a fun (and hardcore) way coming from a Java background. Java is all object oriented so oop is in my blood, but I'm finding that OOP hasn't made it yet to PHP. Most PHP is still being written today the old way without the new concepts. I...

I write a URL router in Python 3.1 and wonder whether it is more than a matter of taste to use one of the following variants: Tuples as constructor params: router = Router( (r"/item/{id}", ItemResource()), (r"/article/{title}", ArticleResource()) ) Method calls router = Router() router.connect(r"/item/{id}", ItemResource())...
Hello. I have an abstract class AbstractEvent and some "real" classes extending it. I want to make an abstract class AbstractListener with a method process(??? event) so that non-abstract classes extending AbstractListener would be required to have at least one method accepting a class extending AbstractEvent. Is that possible? ...

I'm working on a toolbar type application. My current plan is to create a "toolbar" class and a "button" class. The toolbar class would create an instance of the "button" for each item on the toolbar. Each instance of the "button" class would handle its button's GUI events (Mouse Over, Click, etc). I also want to have global options that...
