smarty 中foreach中iteration变量值就是当前循环次数
例子：


{foreach key=key item=item from=$contact name=name}
{$key}: {$item}:{$smarty.foreach.name.iteration}

{/foreach>


注意：得加上：name=name   {$smarty.foreach.name.iteration}  依次循环会显示：1，2，3，4...
详细的例子如下：
HTML:

  




<{$content}>
<{foreach from=$array item=foreach name=name}>
<{$foreach.newsID}>

<{$foreach.newsTitle}>

<{$smarty.foreach.name.iteration}>

<{/foreach}>

PHP:

require "main.php";
$tpl->template_dir = "./aaa";
$array[] = array("newsID"=>1, "newsTitle"=>"第1条新闻");
$array[] = array("newsID"=>2, "newsTitle"=>"第2条新闻");
$array[] = array("newsID"=>3, "newsTitle"=>"第3条新闻");
$array[] = array("newsID"=>4, "newsTitle"=>"第4条新闻");
$array[] = array("newsID"=>5, "newsTitle"=>"第5条新闻");
$array[] = array("newsID"=>6, "newsTitle"=>"第6条新闻");
$tpl -> assign("array",$array);
$tpl -> assign("title","测试标题");
$tpl -> assign("content","Hello,World");
$tpl -> display("test.htm");
?>

main.php

include   "../drivers/smarty/Smarty.class.php";
$tpl= new Smarty();
$tpl->left_delimiter = "<{";
$tpl->right_delimiter = "}>";

?>
