Ok, but if it would be that way I shouldn't get '122334455' for second output, 
no? The item count increments with every iteration of the loop.

Or you're saying that, it checks for an existance of nextitem before every 
loop, and that will fail with just one element, but will always return true 
with two elements? ( since the first elements copy is pushed as third element, 
etc )

Exactly... it's not counting at all. If it were, you wouldn't get to so many iterations with only 2 entries in the array. I can't remember exactly how PHP stores arrays (some kind of bucket structure), but it's likely it traverses the items like a linked list using pointers from one to the next for efficiency.
