    <li data-role="collapsible">	<h1 id="中奖信息">中奖信息</h1>	<ul>		<?php 		$sql = "select * from t_activity where MemberID='$memberID'";		$res = $db->GetData($sql);				while ($obj = mysqli_fetch_object($res))		{			?>			<li><?php echo $obj->字段 ;?></li>			<?php		}				?>			</ul>	</li>

    <li data-role="collapsible">	<h1 id="中奖信息">中奖信息</h1>	<ul>		<?php 		$sql = "select * from t_activity where MemberID='$memberID'";		$res = $db->GetData($sql);				while ($obj = mysqli_fetch_object($res))		{			?>			<li><?php echo $obj->字段 ;?></li>			<?php		}				?>			</ul>	</li>

    大神就是大神!膜拜下!

    还有个问题请教:
    $sql = "select count(*) from t_activity where MemberID='$memberID'";
    $res = $db->ExecSql($sql);
    $num = mysqli_num_rows($res);
    问下mysql,怎么统计查询count(*) 的行数,用上面的方法一直不成功!

    打印出来1,但数据库有3条

    打印出来1,但数据库有3条
    把count(*)换成* 就可以了

    或者这样也可以

    $row = mysqli_fetch_row($res);$num = $row[0];

    大神!

    $num = mysqli_fetch_row($res);
    echo $num[0];

    或者
    list($num) = mysqli_fetch_row($res);

    或者
    $num = crrrent(mysqli_fetch_row($res));
