I'm using CodeIgniter and I have a few utils that I want each controller (that is, each controller file) to have access to.
The question is: where to put these?
I thought of helpers, but the CI documentation talks only about extending existing helpers, not making your own. I'm sure that doesn't mean I can't make my own helpers, but it does mean I don't know how they should be built (procedural? Methods of the global CI instance? etc)
I also considered hooks, but this is a poor fit I think as I'm not extending core functionality.
Or is there some other way I'm missing?
