Listing diary events grouped by days in PHP/MySQL

I’ve got a database which holds live band gigs for my town, each gig is stored as a record in my MySQL database.

I’d like to group by day to see the gigs on my website. But the GROUP BY function will only show 1 record. How can I show all gigs under one date?

My MySQL structure..

ID  date                    content
1   2012-12-02 00:00:00     Gig 1
2   2012-12-02 00:00:00     Gig 2
1   2012-12-03 00:00:00     Gig 1
2   2012-12-03 00:00:00     Gig 2

I’d like to show like this..

-- Sun 02 December 2012 --
Gig 1
Gig 2

-- Mon 03 December 2012 --
Gig 1
Gig 2

Don’t group the results in the database layer, do it in your presentation layer. For example, using PDO:

$dbh = new PDO("mysql:dbname=$dbname", $username, $password);

$qry = $dbh->query('
  SELECT   UNIX_TIMESTAMP(date), content
  FROM     gigs
  WHERE    date > NOW()
  ORDER BY date
');

if ($qry->execute()) {

  // output headers
  echo '<h1>Upcoming gigs</h1>';

  $row = $qry->fetch();
  while ($row) {
    $current_date = $row['date'];

    // output $current_date initialisation
    echo '<h2>', date('D d F Y', $current_date), '</h2><ul>';

    do {
      // output $row details
      echo '<li>', htmlentities($row['content']), '</li>';
    } while ($row = $qry->fetch() and $row['date'] == $current_date);

    // output $current_date termination
    echo '</ul>';
  }

  // output footers

}
