14,609 PointsIs not a bad practice to use globals inside function's scope?
From what I know, using global variables inside function's scope creates a lot of problems, I wonder, why are you using this way of working with function's dependencies? Passing the $db variable as a parameter makes more sense.

Treehouse Guest TeacherHi Pirvan, Yes, there are better ways for accessing the $db variable and we chose to do it this way in the lessons to not have more complexity. The best way to do this would be creating a Database class that holds all of the database functionality and then creating a new instance or using an already instantiated version of that Database class for all functions that need to make CRUD requests.
