输出文件：index.php
复制代码 代码如下:
<?php
require_once('libs/Smarty.class.php');
$smarty = new Smarty();
$smarty->setTemplateDir($_SERVER['DOCUMENT_ROOT']."/php/templates/");
$smarty->setCompileDir($_SERVER['DOCUMENT_ROOT']."/php/templates_c/");
$smarty->setCacheDir($_SERVER['DOCUMENT_ROOT']."/php/cache/");
$smarty->caching = false;
require_once('libs/Smarty.class.php');
$smarty = new Smarty();
$smarty->setTemplateDir($_SERVER['DOCUMENT_ROOT']."/php/templates/");
$smarty->setCompileDir($_SERVER['DOCUMENT_ROOT']."/php/templates_c/");
$smarty->setCacheDir($_SERVER['DOCUMENT_ROOT']."/php/cache/");
$smarty->caching = false;
$name = array("喜洋洋","美洋洋","懒洋洋","哈哈哈");
$family = array("husband"=>"喜洋洋","wife"=>"美洋洋","boy"=>"懒洋洋","girl"=>"哈哈哈");
$smarty->assign("name",$name);
$smarty->assign("family",$family);
$smarty->display("temp.htm");
?>
模板文件：temp.htm
复制代码 代码如下:
{foreach $name as $value}
{$value}
{/foreach}
{foreach $family as $family_name}
{$family_name@key} = {$family_name}
{/foreach}
{foreach from=$family item=f_name key=k}
{$k} = {$f_name}
{/foreach}
{$value}
{/foreach}
{foreach $family as $family_name}
{$family_name@key} = {$family_name}
{/foreach}
{foreach from=$family item=f_name key=k}
{$k} = {$f_name}
{/foreach}
数组的输出方法大致有两种形式：
（1）一种是smarty 2的 {foreach from=数组变量名 item=数组值}。
（2）smarty 3的输出方法与php的一致，上面实例没有加$key，需要输出键名时，采用实例里的形式 @key；你可以使用$key=>$value这种形式。
另外，如果只取数组中某一个值，可以直接输出，如关联数组的 {$family.husband}、索引数组的 {$name[0]}等。
希望本文所述对大家的php程序设计有所帮助。
