smarty模板引擎使用内建函数foreach循环取出所有数组值的方法,smartyforeach

本文实例讲述了smarty内建函数foreach的使用方法,分享给大家供大家参考。具体如下:

显示文件:index.php:

复制代码 代码如下:

//创建smarty对象
require_once("./libs/Smarty.class.php");
$smarty = new Smarty();

$arr1 = array("北京","上海","广州");//索引数组
$smarty->assign("arr1",$arr1);//分配索引数组
$arr2 = array("city1"=>"北京","city2"=>"上海","city3"=>"广州");//关联数组
$smarty->assign("arr2",$arr2);//分配关联数组
$arr3 = array(array("北京","上海","广州"),array("关羽","张飞","美女"));//二维索引数组
$smarty->assign("arr3",$arr3);
$arr4 = array(array("c1"=>"北京","c2"=>"上海","c3"=>"广州"),array("n1"=>"关羽","n2"=>"张飞","n3"=>"美女"));//二维关联数组
$smarty->assign("arr4",$arr4);

$smarty->display("temp.tpl");
?>

模板文件:temp.tpl

复制代码 代码如下:


smarty内建函数foreach,循环取出数组值


实例1:一维索引数组


{foreach from=$arr1 item=temp}
{$temp}
{/foreach}

实例2:一维关联数组——>item为键值,key为键名。如果不取key,取出方法与一维索引数组相同,当然索引数组也是有key的0,1,2...


{foreach from=$arr2 item=temp key=k}
{$k}={$temp}
{/foreach}

实例3:二维索引数组——>两次循环即可


{foreach from=$arr3 item=temp}
 {foreach from=$temp item=value}
  {$value}
 {/foreach}

{/foreach}

实例4:二维关联数组——>同样两次循环即可


{foreach from=$arr4 item=temp}
 {foreach from=$temp item=value key=k}
  {$k}={$value}
 {/foreach}

{/foreach}

希望本文所述对大家的php程序设计有所帮助。
