reset() returns the first element in the array, so it's not such a bad thing that next()
returns the second. To avoid the overhead of using list() with each(), you can simply do this:
$elem = reset($your_array)
do
{
//.. stuff with $elem;
} while($elem = next($your_array));
this is, of course, assuming that the array is not empty, but it's easy to wrap the whole thing
in an if().
