ติดปัญหาเรื่อง radio button ใน loop while ค่ะ จะแก้ยังไงให้ name มันเปลี่ยนตามหัวข้อที่ select ออกมาจากตารางข้อมูล

function radio(){
$sql_group="SELECT * FROM tb_evaGroup ";
    $result_group=mysql_query($sql_group);    
    $rows_group=mysql_fetch_array($result_group); 
    $evaGroupId=$rows_group['evaGroupId'];
    $evaGroupName=$rows_group['evaGroupName'];
       
echo"<tr bgcolor=\"#FFCCCC\">"
  . "<th align=\"left\" colspan=\"5\">".$evaGroupName."</th>"
  . " </tr>";    

$sql="SELECT * FROM tb_evaTopic WHERE evaGroupId = '$evaGroupId'";
echo $sql;
    $result=mysql_query($sql);    
    $topics=mysql_fetch_array($result)
    while($rows=mysql_fetch_array($result)){    
    $topic=$topics['topicName'];
    echo"<tr bgcolor=\"#EEEEEE\">"
      . "<td height=\"25\">".$topic."</td>";
    for($i=4;$i>=1;$i--){
        echo "<td align=\"center\"><input type=\"radio\" value=\"".$i."\" align=\"MIDLE\" name=\"rdoName".$i."\"/ checked=\"checked\" ></td>";
      }  
        echo"</tr>";   
        
  }//end loop while

}

for($i=4;$i>=1;$i--){
        echo "<td align=\"center\"><input type=\"radio\" value=\"".$i."\" align=\"MIDLE\" name=\"rdoName".$i."\"/ checked=\"checked\" ></td>";
      }  

function radio($evaGroupId,$rdoname){
$sql_group="SELECT * FROM tb_evaGroup where evaGroupId='$evaGroupId' ";
    $result_group=mysql_query($sql_group);    
    $rows_group=mysql_fetch_array($result_group); 
    $evaGroupId=$rows_group['evaGroupId'];
    $evaGroupName=$rows_group['evaGroupName'];
       
echo"<tr bgcolor=\"#FFCCCC\">"
  . "<th align=\"left\" colspan=\"5\">".$evaGroupName."</th>"
  . " </tr>";    

$sql="SELECT * FROM tb_evaTopic WHERE evaGroupId = '$evaGroupId'";
//echo $sql;
    $result=mysql_query($sql);    
   $rows=mysql_fetch_array($result);    
    $topic=$rows['topicName'];
    echo"<tr bgcolor=\"#EEEEEE\">"
      . "<td height=\"25\">".$topic."</td>";
    echo "<td align=\"center\"><input type=\"radio\" value=\"4\" align=\"MIDLE\" name=\"$rdoname\"/ checked=\"checked\" ></td>";
    echo "<td align=\"center\"><input type=\"radio\" value=\"3\" align=\"MIDLE\" name=\"$rdoname\"/ checked=\"checked\" ></td>";
    echo "<td align=\"center\"><input type=\"radio\" value=\"2\" align=\"MIDLE\" name=\"$rdoname\"/ checked=\"checked\" ></td>";
    echo "<td align=\"center\"><input type=\"radio\" value=\"1\" align=\"MIDLE\" name=\"$rdoname\"/ checked=\"checked\" ></td>";
    echo"</tr>";   
        
}

  <? radio('1','1')?>
   <? radio('2','2')?>

      }  
        echo"</tr>";
