아래소스에서 새창열기를 할려면!

소스가 아래와 같습니다.

---------------------------------------
<?
//날짜표시
$date = explode("-", $date1);
$year = $date[0];
$month = $date[1];
$day = $date[2];
$latest_date = $year."-".$month."-".$day."";
echo $list[$i]['icon_reply'] . " ";
echo "<a href='{$list[$i]['href']}'>";
if ($list[$i]['is_notice'])
echo "<strong>{$list[$i]['subject']}</strong>";
else
echo "{$list[$i]['subject']}";
echo "</a>";

if ($list[$i]['comment_cnt'])

echo " <a href=\"{$list[$i]['comment_href']}\" style='font-size:9px; color:#EE5A00; vertical-align:1px;'>{$list[$i]['comment_cnt']}</a>";
echo " " . $list[$i]['icon_new'];
echo " " . $list[$i]['icon_hot'];
//echo " " . $list[$i]['icon_file'];
//echo " " . $list[$i]['icon_link'];
//echo " " . $list[$i]['icon_secret'];
echo "</td><td width=36 align=right>";
echo "<font color=#bababa class=small>".substr($list[$i][datetime],5)."</font>&nbsp;</td>";
?></td></tr><? } ?>

추가적으로 클릭을 했을때 새창으로 열게할려면 어떻게 해야되나요?
