在smarty中如何使用恒等于？
我用

<br />
{foreach item=nav from=$navs}<br />
{if $nav.name === $crumbname}<br />
<li class="current"><a href="{$nav.url}">{$nav.name}</a></li><br />
{/if}<br />
<li><a href="{$nav.url}">{$nav.name}</a></li><br />
{/foreach}<br />
Copy after login

没有任何效果。

请问是否===使用不正确？
该如何使用？

eq or neq 不就行了么？

为什么要恒等于，PHP是弱类型语言，设计的时候就不要出现这种问题
