I would like to know, why extending a built-in class in php is important. I mean let's take the PDO class for example. One can either work with using new PDO(); or class Foo extends PDO. to do the same task. I guess, maybe the only thing that makes sense here is, that if I extend the class, there may be less overhead during the scripts run time, because I am working from something within the class, and I may be able to work with public, protects methods and properties, and also add more of those, but that is as …

I just started wondering.. I have a bass class, let's say a class called Framework. This class contains a lot of functions and sets a couple of variables that are used inside other classes. What would be the most efficient way to access these variables from inside other classes? Should I have them extend the Framework class, or should make the variables available in some other way? Side question: if I have 5 classes that all extend the Framework class, does that mean that the Framework class is instantiated and constructed 5 times during the execution of the script?

The sort methods for collections specifies that the parameter must be a collection of objects that implement Comparable for their own class or superclass, eg [CODE]public static <T extends Comparable<? super T>> void sort(List<T> list)[/CODE] Can anyone tell me how to define an ArrayList that will only accept such objects? I want to say [CODE]ArrayList<T extends Comparable<? super T>> eg = new ArrayList<String>();[/CODE] But that doesn't compile. I could use [CODE]ArrayList<? extends Comparable<?>> ok = new ArrayList<String>();[/CODE] but that's a bit too general (although the exceptions would be weird anyway). I know I'm going to look silly when someone points …

Hello, I have a page that I want to have borders on all 4 sides. The problem is, the bottom border does not extend to the bottom of the page. It stops mid-way, with content extending below it.
