Numerating Comments

Question

下面的代碼按時間順序打印給定「submissionid」的所有註釋。我怎麼能計算這些評論？ （換句話說，我怎麼打印出「1」旁邊的最古老的評論，一個「2」旁邊的第二古老的評論，等等？）

$submission = mysql_real_escape_string($_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>"

顯示的代碼相關的部分，休息註釋掉，所以你馬上看到我加了什麼：

//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>";
