If you use getInstance(), a constructor gets called - which is often handy
if you need to run any kind of initialisation code for your singleton (that
you couldn't just do with initial property values).
If you just used statics, you might end up having to do something like:
public static function doSomething()
{
if (!_initialised)
{
_initialiseMe();
}
// Do whatever this function is supposed to.
}
for every function that cared about the initialisation. Which is a pain.
I often pre-emptively use getInstance in case I need to go back and add any
sort of initialisation to a class later on. If it's clearly a utility only
class (for example, string utilities, math utilities - just a collection of
helper functions in a class) then I tend to use purely statics.
Cheers,
Ian
