smarty模板引擎中变量及变量修饰器用法实例_PHP

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}

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

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 [e-mail]";
$str2 = "[e-mail]";
$smarty->assign("str",$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");
