请教:查询DB后相同类型的记录合并为一行显示且可展开。
数据在DB中存储如上图,现在要在页面如下图显示,即:相同编码的记录显示为一行,且将“费用”列做加法;点击加号可展开为实际记录。

------解决方案--------------------

<br />$res =mysql_query(select 工程,编码,sum(费用) from table group by 编码)<br />foreach($res as $k=>$v){<br />   $res[$k]['child']  =  mysql_query(select 工程,编码,费用 from table where 编码=$v['编码']);<br />}<br />echo '<table><tr><td>工程</td><td>编码</td><td>费用</td></tr>';<br />foreach($res as $v){<br />   echo '<tr><td>$v['工程']</td><td>$v['编码']</td><td>$v['费用']</td></tr>';<br />   foreach($v['child'] as $vv){<br />      echo '<tr   style="max-width:90%"><td>$vv['工程']</td><td>$vv['编码']</td><td>$vv['费用']</td></tr>';<br />   }<br />}<br />echo '</table>';<br />
