php 广告调用类代码(支持Flash调用)

调用方式如下：其中debugstr这个函数就是类似一个echo。

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：
