    22.     </tr>
    23. <?php
    24. $res=mysqli_query($conn,"SELECT * FROM users");
    25. while($row=mysqli_fetch_array($res))
    26. {
    27.     echo "<tr>";
    28.     echo "<td>"; ?> <input type="checkbox" name="num[]" class="other" value="<?php echo $row["id"]; ?>" /> <?php echo "</td>";
    29.     echo "<td>"; echo $row["ids"]; echo "</td>";
    30.     echo "<td>"; echo $row["usernames"]; echo "</td>";
    31.     echo "<td>"; echo $row["passwords"]; echo "</td>";
    32.     echo "<td>"; echo $row["emails"]; echo "</td>";
    33.     echo "</tr>";
    34. }
    35. ?>

    43.    while (list ($key,$val) = @each ($box))
    44.     {
    45.       mysqli_query($conn,"DELETE FROM users WHERE id='$val'");
    46.     }
    47. ?>
    48.        <script type="text/javascript">
    49.        window.location.href=window.location.href;
