Where to put global php in Laravel application

Sorry if this is a silly question or has been answered before, but I just need a quick bit of advice!

Where is the best place in a Laravel 5 application to apply global php settings and why?

For example, if I want to set

ini_set('max_input_vars','10000');

and other various code that will be set globally across the application, where is best practise put it?

Please can someone properly explain where and why?
