Lets say I have a table with 1 column having a list of months:
Jan, Jan, Feb, Jan, Feb, Feb, Jan, Feb
And another column having a list of dates associated with those months:
1,2,5,7,14,12,30,16

I want to view the results like this:
Jan
1
2
7
30

Feb
5
14
12
16

Here is what I'm working with:

<?php
$sql="SELECT month, day FROM calendar GROUP BY month";
$sql2="SELECT month, day FROM calendar ORDER BY month";
$result=mysql_query($sql);
$result2=mysql_query($sql2);
while($rows=mysql_fetch_array($result)){
?>
<table><tr><td>
<?php echo( $rows['month'] ); ?>
</td></tr><tr><td>
<?php
while($rows2=mysql_fetch_array($result2)){
echo $rows2['day'] ;?>

 }
?>
</td></tr></table>
<?php
 }
?>

I'm getting 2 tables - Jan & Feb, but all the dates go in Jan. I can see why it's doing that. I can't figure out how to get the Feb dates over in the Feb table. Thanks for any suggestions or direction.

$months = array(
1 => 'January',
2 => 'February',
3 => 'March',
4 => 'April',
5 => 'May',
6 => 'June',
7 => 'July',
8 => 'August',
9 => 'September',
10 => 'October',
11 => 'November',
12 => 'December'
);

$months_flip = array_flip($months);

$result = mysql_query("SELECT month, day FROM calendar ORDER BY month, day") or exit(mysql_error());
while ($row = mysql_fetch_assoc($result)) {$dates[$months_flip[$row['month']]][] =  $row['day'];}

foreach ($dates as $key => $value)
{
	echo $months[$key] . '<br>';
	foreach ($value as $sub_value)
	{
		echo $sub_value . '<br>';
	}
	echo '<br>';
}
