Hi, first of all i hope this is not a duplicate thread, if so please point me in the right direction i couldn't find anything related.
The issue is that I'm rather new to web development and I thought it might be a good idea to use the mvc architecture (no framework, i want to know how things work from scratch). Now I think I have understood the concept (as explained in sitepoint tutorial, maybe somebody can shed some light on the different "versions" of mvc?) but i don't know where I should put standard methods like converting an array to a string, mysql methods of all kind and so on. They don't really seem to fit in the model because the contain markup sometimes, but also not in the view because sometimes they fetch or manipulate data.
Currently I have:
-other stuff like filehoster save locations
Also the app folder contains only static information at the moment, am I doing that right? Doesn't feel right...
Thanks for your help in advance, kind regards
