It can happen that you need to pass a lot of variables. Passing over classes through an array is still very bad practice. Especially because when you do so, you can't define the type. You're taking away a lot of strength of PHP by doing do. I highly, and I can't stress this enough, no matter what reason, do not advice to pass along data like that. Unless it's for example an array of strings that are all going to be used in the same way (for example, to sort a list or something)
