smarty模板引擎中变量及变量修饰器用法实例

前端技术 2023/09/09 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：

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\");
?>
