thinkphp <if>标签 condition中可以写PHP的判断逻辑

<ul>
    <volist name="monthArray" id="monthItem">
        <if condition="$monthItem eq I('get.monthParam') ">
        <li>
            <a href="{:U('accountInfo', array('monthParam'=>$monthItem))}"
               class="selectItem">{$monthItem}</a>
        </li>
        <else/>
        <li>
            <a href="{:U('accountInfo', array('monthParam'=>$monthItem))}">{$monthItem}</a>
        </li>
        </if>
    </volist>
</ul>
