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 )

Ahhh... you want the behaviour of the multiple elements... I presumed 
you wanted the other way around.

You're making an assumption that it is checking the count. It may just 
be pre-determining whether another element exists for the next 
iteration. Consider the following pseudo code:

     nextItem = items->reset();
     while( nextItem )
         item = nextItem;
         nextItem = items->next();

         // Do stuff.

There's lots of ways to program a loop... and your PHP foreach loop is 
being converted to something entirely different internally. The above 
doesn't count elements, but it will result in the same behaviour as you 
are experiencing.
