[函数运用] 【管道符】
{$email}:{$email|md5}
{$email}:{$email|substr=0,8}
{$email}:{$email|substr=###,0,8}
{$time}:{$time|date="Y-m-d",###}
substr($obj,0,3);
md5($obj);
date('Y-m-d',time());
[计算]
<body>
<h1>这是view/index/index.html</h1>
//Controller由assign()的时候
<p>a+b={$a+$b}</p>
<p>{++$a}</p>
<p>{--$a}</p>
//Controller无assign的时候，可以设默认值
{$email|default="25478@qq.com"}
</body>
[原样输出]【literal标签】
<p>
{literal}
{$email}
