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：

复制代码 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}   dosomething  帅锅 {$smarty.server.SERVER_NAME}{$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
复制代码 代码如下:
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 "
";print_r($family);$smarty->display("temp.htm");?>
