Question

     if ($num_rows > 0)
                {
                    while($row=mysql_fetch_assoc($res))
                    {
                        $fromuser=$row['username'];
                        $comment=$row['comment'];
                        $commentdate=$row['date'];

                        $date=strtotime($commentdate);
                        $final_date=date("g:i a", $date);  
                        $final_date2=date("F j Y", $date);

            ?>


            <table align="center" width="100%"style='border-top: 1px dotted;'bgcolor="#eeeeee" >
            <tr><td><?echo "<a href=\"userprofile.php?user=$fromuser\"><b>$fromuser</b></a> commented:\n";?></td></tr>
            <tr><td><?echo "at $final_date on $final_date2\n";?></td></tr>
            <tr bgcolor="#ffffff"><td><?echo "$comment\n";?></td></tr>
            </table><br>
            <?
                    }
                }
                else 
                {
                    echo"There are currently no comments on this user";
                }
            ?>

我正在寻找一种方法来为每条评论添加一个数字。所以在DESC顺序中有1,2,3,4等。我想不出我怎么能这样做？

我在您的代码中添加了几行，可以实现您想要的效果。

 if ($num_rows > 0)
                {
                    $number = $num_rows;
                    while($row=mysql_fetch_assoc($res))
                    {
                        $fromuser=$row['username'];
                        $comment=$row['comment'];
                        $commentdate=$row['date'];

                        $date=strtotime($commentdate);
                        $final_date=date("g:i a", $date);  
                        $final_date2=date("F j Y", $date);

            ?>


            <table align="center" width="100%"style='border-top: 1px dotted;'bgcolor="#eeeeee" >
            <tr><td><?echo $number;?><td><?echo "<a href=\"userprofile.php?user=$fromuser\"><b>$fromuser</b></a> commented:\n";?></td></tr>
            <tr><td><?echo "at $final_date on $final_date2\n";?></td></tr>
            <tr bgcolor="#ffffff"><td><?echo "$comment\n";?></td></tr>
            </table><br>
            <?
                    $number -= 1;
                    }
                }
                else 
                {
                    echo"There are currently no comments on this user";
                }
            ?>

Answer 2

$counter = $num_rows;
  while($row=mysql_fetch_assoc($res))
                    {
{
// ... your code

$counter -= 1;

echo $counter;
}
