本文实例讲述了smarty变量及变量修饰器的应用。分享给大家供大家参考。具体如下：
模板文件：temp.htm：
代码如下:
{config_load file="foo.conf"}
{$name.na1|cat:$name['na2']}
{$name['na1']|cat:'与'|cat:$name.na2}
{foreach from=$name item=na}
{$na}
{/foreach}
{$dog->leee()}{$dog->name}
<script><br>
{literal}<br>
function foobar{<br>
alert('foobar!');<br>
}<br>
{/literal}<br>
</script>

{$smarty.server.SERVER_NAME}
{$str|count_words}
-------常量--------
{$smarty.now}
{$smarty.const.MY_CONST}
{$smarty.template}
{$smarty.current_dir}
{$smarty.version}
{$smarty.ldelim|cat:$smarty.rdelim}
{$smarty.now|date_format:$config}
{$yesterday|date_format:'Y-m-d'}
{$string|default:'default变量修饰：smarty学习'}
{$str1|escape:'html'}
{$str2|escape:'mail'}
{$str1|indent|upper}
{$str1|nl2br}
{$str1|regex_replace:"/@\d{3}/":"ABC"}
{$str1|replace:"163":"sina"}
{$str1|spacify}
{$number|string_format:"%.2f"}
{$number|string_format:"%d"}
{$str3|strip:"|"}
去除包含在之间的字符：{$str3|strip_tags}
截取长度：{$str3|truncate:10:"...":true}
按长度换行：{$str3|wordwrap:30:"
"}
{append var='name' value="Bob" index="first"}
{append var='name' value="John" index="last"}
{$name.last}
{foreach from=$family item=home}
{foreach from=$home item=person}
{$person}
{/foreach}
{/foreach}
{$family[1].girl}
{assign var="name" value="张三丰"}
{$name}
php文件：index.php
代码如下:
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;
$arr = array("na1"=>"帅锅","na2"=>"美女");
$smarty->assign("name",$arr);
class Dog{
public $name;
public $age;
function leee(){
return $this->name."在干吗";
}
}
$dog = new Dog();
$dog->name="小狗";
$smarty->assign("dog",$dog);
//$str = "hello world,i am here. i love smarty!";
$str = "帅锅";
$str1 = "新浪 And\n aassu@163.com";
$str2 = "aassu@163.com";
$smarty->assign("str",$str);
$smarty->assign("str1",$str1);
$smarty->assign("str2",$str2);
$smarty->assign("number",30.293934);
$smarty->assign("str3","akie abfal ,dooerw，show databases,desc table");
$config = "Y-m-d H:i:s";
$smarty->assign("config",$config);
$smarty->assign("yesterday",strtotime('-1 day'));
//常量
define("MY_CONST","百度");
//append成员方法的使用
$family = array("husband"=>"帅锅","wife"=>"美女");
$famiadd = array("boy"=>"张三丰","girl"=>"王昭君");
$smarty->append("family",$family);
$smarty->append("family",$famiadd);
echo "
";<br>
print_r($family);<br>
$smarty->display("temp.htm");<br>
