In PHP, is there any performance impact on using one long class with a lot of functions in it? Or is it advisable to use many small classes and call them separately when needed?
I am a newbie in OOPS and please ignore any silliness in the question. Thanks...

Very long classes with a lot of methods and properties are very difficult to understand.
Can and should put things in the same class as long they are directly related to the logicFirst, think about clean OOP design.

Let me explain, this is about displaying class source code in IDEs. I have always only one class per file. A class is declared like this in the file mod1.js:
MYGLOB.MOD1.ClassXy = function () { //constructor, do somothing } MYGLOB.MOD1.ClassXy.prototype...

When is a function too long? is a subset of this question, I think.

Hi,
I have two geo-spatial simple convex polygon areas, in latitudes and longitudes (decimal degrees) that I want to compute using Javas Polygon class. I basically want to see if these two lat,long polygons intersect, and to calculate the areas (in sq...

I have a (for me) complex object with about 20 data member, many of which are pointer to other classes. So for the constructor, I have a big long, complex initialization list. The class also has a dozen different constructors, reflecting the various ways...

When you need to have very small objects, say that contains 2 float property, and you will have millions of them that aren't gonna be "destroyed" right away, are structs a better choice or classes?
Like in xna as a library, there are point3s, etc as structs...

If you have that many of them they're likely part of a class instance (on the heap valueS" implies their storage on the heap somewhere, probably an array field of a class instance.
It's that big of a deal.

I've got a bunch of functions that I want to move into a class. They're currently split into a couple of fairly long files. I'd prefer not to have one 2500 line file, but as far as I can tell, you can't use include to split a class up into multiple files...

Also, I tend to make the $this variables in the Page class, but still group it into another class.
