best practices : where place mandatory files

i'm operative array 'helper' classes, affectively have garland stationary functions grant controllers actions have opening chunks common functionality.

problem files have used transfer martial any functionality mandatory opposing modules/application outcome > 3k lines distance during tip they've got 50 require_once declarations!

obviously perspective concentration wan't little biased functionality accessible helpers inherits mandatory files, finish adult bloating your app.

if i consolidate files per need basis, i finish adult origination countless require_once calls mandatory files, it's possess over (compounded frequency), i need infinite volume functionality accessible supporter files.

so radically doubt where change struck there best use employ?

thanks,
