smarty模板引擎使用内建函数foreach循环取出所有数组值的方法

$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","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"); ?>

smarty内建函数foreach，循环取出数组值

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

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}

两次循环即可

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

同样两次循环即可

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