You're looking for this one:
你正在寻找这个：
{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 $smarty.foreach.foo.lastwhere foois the name of your object.
如您所见，您需要检查的属性是对象的名称$smarty.foreach.foo.last在哪里foo。

If $arr is the array you passed to the {foreach}, this will do the trick:
如果 $arr 是您传递给 {foreach} 的数组，这将起作用：
{$arr|@end}
In fact, it does not have to be called inside a {foreach}
事实上，它不必在 {foreach} 中调用

I think newer versions of Smarty have a newer technique of solving this problem than what the other answers show. The example from the latest docs(at the time of writing) is using the @last-property. You can use it like this: {if $item@last}...
Complete example:
我认为较新版本的 Smarty 具有比其他答案显示的更新的技术来解决这个问题。最新文档中的示例（在撰写本文时）正在使用@last- 属性。您可以像这样使用它：{if $item@last}...
完整示例：
{* Add horizontal rule at end of list *}
{foreach $items as $item}
<a href="#{$item.id}">{$item.name}</a>{if $item@last}<hr>{else},{/if}
{foreachelse}
... no items to loop ...
{/foreach}

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

This actually worked for me:
这实际上对我有用：
{$myvar=$someArray@end}
{$myvar.someproperty}
