smarty模板引擎中变量及变量修饰器用法实例

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}
<script>
{literal}
function foobar{
 alert(foobar!);
}
{/literal}
</script>
<title>{#pageTitle#}</title>
<body bgcolor="{#bodyBgColor#}">
<table border="{#tableBorderSize#}" bgcolor="{#tableBgColor#}" >
 <tr bgcolor="{#rowBgColor#}">
  <td>dosomething</td>
  <td>帅锅</td>
 </tr>
</table>
{$smarty.server.SERVER_NAME}
<hr />
{$str|count_words}
<hr />
-------常量--------<br>
{$smarty.now}<br />{$smarty.const.MY_CONST}<br />{$smarty.template}<br />{$smarty.current_dir}<br />{$smarty.version}<br />{$smarty.ldelim|cat:$smarty.rdelim}
<hr />
{$smarty.now|date_format:$config}
{$yesterday|date_format:Y-m-d}
<hr />
{$string|default:default变量修饰：smarty学习}
<hr />
{$str1|escape:html}<br />{$str2|escape:mail}
<hr />
<p>{$str1|indent|upper}</p>
{$str1|nl2br}
<hr />
{$str1|regex_replace:"/@\d{3}/":"ABC"}<br />
{$str1|replace:"163":"sina"}<br />
{$str1|spacify}<br />
<hr />
{$number|string_format:"%.2f"}<br />
{$number|string_format:"%d"}<br />
<hr />
{$str3|strip:"|"}<br />
去除包含在<>之间的字符：{$str3|strip_tags}<br />
截取长度：{$str3|truncate:10:"...":true}<br />
按长度换行：{$str3|wordwrap:30:"<br />"}
<hr />
{append var=name value="Bob" index="first"}
{append var=name value="John" index="last"}
{$name.last}<br />
{foreach from=$family item=home}
{foreach from=$home item=person}
{$person}
{/foreach}
{/foreach}
{$family[1].girl}
<hr />
{assign var="name" value="张三丰"}
{$name}
</body>

php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;
$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 = "<a href=http://www.sina.com/>新浪</a> 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   <a;fa>,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 "<pre>";
print_r($family);
$smarty->display("temp.htm");
?>

希望本文所述对大家的php程序设计有所帮助 。
