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：
{config_loadfile="foo.conf"}
{$name.na1|cat:$name['na2']}
{$name['na1']|cat:'与'|cat:$name.na2}
{foreachfrom=$nameitem=na}
{$na}
{/foreach}
{$dog->leee()}{$dog->name}
<script>
{literal}
functionfoobar{
alert('foobar!');
}
{/literal}
</script>
<title>{#pageTitle#}</title>
<bodybgcolor="{#bodyBgColor#}">
<tableborder="{#tableBorderSize#}"bgcolor="{#tableBgColor#}">
<trbgcolor="{#rowBgColor#}">
<td>dosomething</td>
<td>帅锅</td>
</tr>
</table>

{$smarty.now}<br/>{$smarty.const.MY_CONST}<br/>{$smarty.template}<br/>{$smarty.current_dir}<br/>{$smarty.version}<br/>{$smarty.ldelim|cat:$smarty.rdelim}

{$str1|nl2br}
<hr/>
{$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/>
