shell i format my numbers 1234.20 => 1'234.20 in model or in view using php and codeigniter?
回答1:
It belongs to the view layer.
The model only cares about the value, not how you present it to the user. Also, you may need to display it differently, if your site is multilingual.
回答2:
In the view, since the transformation is presentational in nature.
回答3:
I would format it in the view, because this sperates the visual from the rest.
