处理方法

PHP code

-->
$sql="select * from newes where advertisingid =1";
$abc =mysql_query($sql);
/**
while($num =mysql_fetch_array($abc))
{
    $num
}
*/

问：就是用什么方法返回一个实体类
比如 Newes $newes = new Newes();
$newes =mysql_query($sql); //这样子就是返回一个实体类么？
超级新手迷糊中····请帮忙解释一下 谢谢

------解决方案--------------------
两段代码之间有神马关系？？
第一个返回实体类
第二个mysql_query返回resource类型的结果集
------解决方案--------------------
形如： private int advertisingid; 改为 private $advertisingid;

你那套是java里面的定义方法吧。
------解决方案--------------------
mysql_fetch_row()
mysql_fetch_array()
mysql_fetch_assoc()

具体区别，请谷歌查。
