列举评论

Question

下面的代码按时间顺序打印出给定"submissionid"的所有注释.我怎么能算出这些评论呢？(换句话说,如何打印最旧评论旁边的"1",第二个最老评论旁边的"2"等？)

$submission = mysql_real_escape_string($_GET['submission']);
$submissionid = mysql_real_escape_string($_GET['submissionid']);

$sqlStr = "SELECT comment.comment, comment.datecommented, login.username
FROM comment
LEFT JOIN login ON comment.loginid=login.loginid
WHERE submissionid=$submissionid
ORDER BY comment.datecommented ASC 
LIMIT 100";         

$result = mysql_query($sqlStr);

$arr = array(); 
echo "<table class=\"commentecho\">";
while ($row = mysql_fetch_array($result)) { 
    echo '<tr>';
    echo '<td class="commentname1">'.stripslashes($row["comment"]).'</td>';
    echo '</tr>';
    echo '<tr>';
    echo '<td class="commentname2"><a href="http://www...com/sandbox/members/index.php?profile='.$row["username"].'">'.$row["username"].'</a>'.date('l, F j, Y &\nb\sp &\nb\sp g:i a &\nb\sp &\nb\sp  \N\E\W &\nb\sp \Y\O\R\K &\nb\sp \T\I\M\E', strtotime($row["datecommented"])).'</td>';
    echo '</tr>';
    }
echo "</table>"

显示代码的相关部分,休息注释掉,以便您立即看到我添加的内容:

//echo "<table class=\"commentecho\">";
$count = 1; //<-start counter
//while ($row = mysql_fetch_array($result)) { 
    //echo '<tr>';
    echo '<td>'.$counter++.'</td>'; //<-use numbering and increment afterwards

    //echo '<td class="commentname1">'.stripslashes($row["comment"]).'</td>';
    //echo '</tr>';
    //..
    }
//echo "</table>";
