Answer 1

If $arr is the array you passed to the {foreach}, this will do the trick:

{$arr|@end}

In fact, it does not have to be called inside a {foreach}

Answer 2

{foreach from=$foo item=$bar name=foo}
    {if $smarty.foreach.foo.last}
        Total of({$smarty.foreach.foo.total}) Items <br />
        Data ({$bar})
    {/if}
{/foreach}

Answer 3

Your looking for this one:

{foreach from=$cityList key=myId item=i name=foo}
    {if $smarty.foreach.foo.last}
        <p>This is the last item from the array!</p>
    {/if}
{/foreach}

As you see, the property you need to check is $smarty.foreach.foo.last where foo is the name of your object.
