The code is very different. In your x() function you create a new array
every time you call x(). In the class example, you create the array once
when you instantiate the class and then return that same array each time
you call the gety() method. When PHP iterates over arrays, it maintains
an array cursor so it knows where in the array it is. Since you keep
returning the same array, the array cursor is kept.
