php - 如何在 PHP 中用 lis 填充剩余空间？

Question

MySQL

+-- -+----------+
| id | whatever |
+----+----------+
| 1  |  blah1   |
+----+----------+
| 1  |  blah2   |
+----+----------+
| 1  |  blah3   |
+----+----------+

PHP

echo '<ul>'

$a = mysql_query("SELECT * FROM table WHERE id = '1' LIMIT 10");
while($b = mysql_fetch_assoc($a))
{
    echo '<li>'.$b['whatever'].'</li>';
}

echo '</ul>';

输出:

<ul>
    <li>blah1</li>
    <li>blah2</li>
    <li>blah3</li>
</ul>

但是，我想要做的是用7个空lis填充剩余空间(在上面的情况下)。

所以，输出应该是:

<ul>
    <li>blah1</li>
    <li>blah2</li>
    <li>blah3</li>
    <li></li>
    <li></li>
    <li></li>
    <li></li>
    <li></li>
    <li></li>
    <li></li>
</ul>

echo '<ul>'

$a = mysql_query("SELECT * FROM table WHERE id = '1' LIMIT 10");
while($b = mysql_fetch_assoc($a))
{
    echo '<li>'.$b['whatever'].'</li>';
}

for ($i = mysql_num_rows($a); $i < 10; $i++) {
    echo '<li></li>';
}

echo '</ul>';
