How do you format your PHP code...
Do you use Tabs or Spaces to indent?
And by how many positions do you indents?
I think a standard line is 80 characters, so I'm starting to wonder if using a 4-position indent is too much?!
(It is easier to read than a 2-position indent, but also seems to waste space?!)
I am using NetBeans as an IDE, and it allows you to change whether us use Tabs or Spaces to indent, and by how much you indent.
What do you do and why?
