调用方式如下：其中DebugStr这个函数就是类似一个echo。
复制代码 代码如下:
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 '<hr>';
类如下：
