查询数组中摸个字段的个数？解决思路

$r=mysql_query('select orderid,zhuangtai,group_concat(`name`) as name,group_concat(`shouji`) as shouji,group_concat(`sex`) as sex from `order` group by orderid');<br /> echo "<table width=950 border='1px solid'>";<br /> echo "<tr><th>姓名</th><th>手机</th><th>性别</th></tr>";<br />while($row=mysql_fetch_assoc($r)){<br />    $shouji_arr=explode(',',$row['shouji']);<br />    $sex_arr=explode(',',$row['sex']);<br />    echo "<td colspan=3>订单号：".$row[orderid]."  状态：".$row['zhuangtai']."</td>";<br />    foreach(explode(',',$row['name']) as $k=>$v){<br />         echo "<tr>";<br />         echo "<td>$v</td><td>$shouji_arr[$k]</td><td>$sex_arr[$k]</td>";<br />         echo "</tr>";<br />    }<br />}<br />echo "</table>";

<td>$v</td><td>$shouji_arr[$k]</td><td>$sex_arr[$k]</td>
