How to do 1,2,3,4 -> array(1,2,3,4)...?

Question

PHP

Hello.
Need to do this:

1,2,3,4 -> array(1,2,3,4)
1 2 3 4 -> array(1,2,3,4)
1\n2\n3\n4 -> array(1,2,3,4)
1,2 3,4 -> array(1,2,3,4)
1\n2,3 4 -> array(1,2,3,4)

I think I showed it clearly, that is, I need a string with numbers that can be separated by (comma) (space) (hyphen), and whatever their combination, in place, out of place, you need to create an array with them.
Thank you!
