C   type2
D   type1
E   type3

2-Jan

Answer 1

It is possible to do this at the database level:

SELECT concat(date, concat('\n__________\n', 
              group_concat(concat(concat(name, '\t'), type) SEPARATOR '\n')))
FROM table_name
GROUP BY date;

You probably should do it at the application level: When you iterate over the result set, check if the current date is different from the date of the previous row to detect group changes.

Edit based on the added PHP code in the question

So something like this:

$lastDate = null;
while($row = mysql_fetch_assoc($result)) {
    if ($row['date'] != $lastDate) {
        echo '<tr><td colspan="2">'.htmlspecialchars($row['date']).'</td></tr>';
        $lastDate = $row['date'];
    }
    echo '<tr>';
    echo '<td><a href="g.php?title='.urlencode($row['s_title']).'">'
              .htmlspecialchars($row['s_title']) .'</a></td>';
    echo '<td><a href="p.php?title='.urlencode($row['p_name']).'">'
              .htmlspecialchars($row['p_name']).'</a></td>';
    echo '</tr>';
}
