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_PHP教程

$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");
?>

smarty内建函数foreach，循环取出数组值

实例1：一维索引数组

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...

实例3：二维索引数组——>两次循环即可

实例4：二维关联数组——>同样两次循环即可
