php - 如何在smarty中显示数组？

Question

我想用 smarty 生成这样的数组结果 ['element1','element2','element3']。我正在使用 PHP 和 smarty。该数组由 PHP 生成，然后由 smarty 按上述格式或样式输出。我的 PHP 代码是这样的:

$countries = array('America','Germany','Japan');

我想在Smarty中显示同样的数组内容，但是这次在smarty中应该这样显示结果

['America','Germany', 'Japan']

有人能帮我吗？谢谢!

检查 foreach loop这里
PHP 代码

$countries = array('America','Germany','Japan');
$smarty->assign('countries', $countries);

智能代码

[
{foreach from=$countries item=country}
    {assign var='total' value=$countries|@count}         {* This stores the total no. of elements in COUNTRIES array in TOTAL variable *}
    {counter assign="count"}                             {* This assigns a counter to COUNT variable *}
    '{$country}'
    {if $count lt $total}
    ,                                                    {* This condition adds ',' after each element of the array until and unless the loop reaches the last element. When the last element reached, this condition won't add ',' *}
    {/if}
{/foreach}
]
