PHP实现节假日剩余天/时/分/秒，例如春节、中秋、国庆這些节日
如图：
=========HTML========
<div class="festival radius mb40 after">
<ul>
<li>
<img src="/static/uzstyle/images/icon-festival1.png" alt="万圣节">距离
<span>万圣节</span> 还有
<span>36 天</span>
</li>
<li>
<img src="/static/uzstyle/images/icon-festival2.png" alt="感恩节">距离
<span>感恩节</span> 还有
<span>63 天</span>
</li>
<li>
<img src="/static/uzstyle/images/icon-festival3.png" alt="黑五">距离
<span>黑五</span> 还有
<span>64 天</span>
</li>
<li>
<img src="/static/uzstyle/images/icon-festival4.png" alt="圣诞节">距离
<span>圣诞节</span> 还有
<span>90 天</span>
</li>
</ul>
</div>
