{foreach},{foreachelse}用于像访问序数数组一样访问关联数组
Attribute Name属性名称
from：循环访问的数组
item：当前元素的变量名
key：当前键名的变量名
name：用于访问foreach属性的foreach循环的名称
{foreach from=$variable item = item key = key name=name}
{$variable|@count} //获取循环数组的长度
{$smarty.foreach.name.index} //获取当前循环数组元素的下标，以0开始
{$smarty.foreach.name.iteration} //获取循环次数，以1开始
{$smarty.foreach.name.first} //当为true时，标记循环第一次执行
{$smarty.foreach.name.last} //当为true时，标记循环最后一次执行
{$smarty.foreach.name.show} //当前是否显示
{$smarty.foreach.name.total} //循环次数
{/foreach}

$arr = array(1000, 1001, 1002);
$smarty->assign("myArray", $arr);
?>

{foreach from=$myArray item=foo}
{$foo}
{/foreach}

1000
1001
1002
Example 7-6. Demonstrates the item and key attributes

$smarty->assign("items", $items_list);
?>
Template to output $items with $myId in the url
{foreach from=$items key=myId item=i}
{$i.no}: {$i.label}
{/foreach}

2456: Salad
4889: Cream
Example 7-8. {foreach} with nested item and key

The template to output $contact.
{foreach name=outer item=contact from=$contacts}
{foreach key=key item=item from=$contact}
{$key}: {$item}
{/foreach}
{/foreach}
The above example will output:
phone: 1
fax: 2
cell: 3
phone: 555-4444
