调用方式如下：其中DebugStr这个函数就是类似一个echo。
<div class="codetitle"><a style="CURSOR: pointer" data="39422" class="copybut" id="copybut39422" onclick="doCopy('code39422')"> 代码如下:<div class="codebody" id="code39422">
DebugStr('$Adv->getContentById($id); $id为广告编号， 仅调用一条，返回内容为字符串');
echo Adv::getContentById(35);
DebugStr('$Adv->getContentByIdJS($id); $id为广告编号， 仅调用一条，返回内容为JS字符串');
echo Adv::getContentByIdJS(35);
DebugStr('$Adv->getContentByOrder($id); $id为广告编号， 仅调用ID倒序一条，返回内容为字符串');
echo Adv::getContentByOrder(4);
DebugStr('$Adv->getContentByOrderJS($id); $id为广告编号， 仅调用ID倒序一条，返回内容为JS字符串');
echo Adv::getContentByOrderJS(4);
echo '
';
类如下：
<div class="codetitle"><a style="CURSOR: pointer" data="31136" class="copybut" id="copybut31136" onclick="doCopy('code31136')"> 代码如下:<div class="codebody" id="code31136">
<?php

说明：广告类，方便广告列表、内容的调用。
需要：数据库类
支持：仅支持PHP5，单件模式
