The code below works great for listing each class in rows and I’ve got it sorted ASC from date and time BUT now I’d like to rearrange it so the classes that occur on Monday appear in order again by start time ASC in column one then continue the loop so classes that occur on Tuesday appear in column two and so on through the week. I’m not sure of the best method or even if I need to rewrite my foreach statements. I’ve tried switch using strings where each case would equal the days “Monday”, “Tuesday”, etc. 

<table>
<tr>
<th width="80">Day</th>
<th width="80">Class</th>
<th width="80">Instructor</th>
<th width="80">Start</th>
<th width="80">End</th>
<th width="80">Studio</th>
</tr>
 <?php
 foreach ($data as $key => $row) 
 {
    $start_date[$key] = $row['Calendar']['start_date'];
    $start_time[$key] = $row['Calendar']['start_time']; 
 }
 array_multisort($start_date, $start_time, $data);

 foreach ($data as $row) {
  <tr>
  <td><?php $row['Calendar']['start_date']; ?></td>
  <td><?php $row['Calendar']['title']; ?></td>
  <td><?php $row['Calendar']['instructor']; ?></td>
  <td><?php $row['Calendar']['start_time']; ?></td>
  <td><?php $row['Calendar']['end_time']; ?></td>
  <td><?php $row['Calendar']['location']; ?></td>
  </tr>
  </table>

SQL

SELECT DAYOFWEEK(start_date) as day_index, title, start_time, end_time, location FROM calendars WHERE calendar_category_id = '3' AND location = 'Studio 1' ORDER BY day_index

got it by:

$calendar = array(); 
foreach ($data as $row) { 
$calendar[$row[0]['day_index']][] = $row;
}

    Are you getting this data from a database? If so you might want to consider changing up your query to get this different grouping. Perhaps something like this:

    SELECT DAYOFWEEK(date_field) AS day_index, [... other class fields ...]
FROM table
ORDER BY day_index ASC;

    Then you could read your data into a two-dimensional array like this:

    $calendar = array();
while ($row = $db_result->fetch() ) { // or whatever you use to iterate through the result set.
    $calendar[$row['day_index']][] = $row;
}

    This gives you an array like this:

    Array(
    '1' => Array(
         0 =>  Array(
             'day_index' =>  '1',
             ... other class fields ...
         ),
         1 =>  Array(
              'day_index' => 1,
             ... other class fields ...
         ),
         ... other class arrays from the result set ...
         ),
    '2' => ... Another numerically indexed array of class arrays for Monday classes ...
    '3' => ... Another numerically indexed array of class arrays for Tuesday classes ...
    ... and so on
)

    Then it comes down to how you are displaying your data. I would think that in order to do what you want to do, you might need to go away from the table based layout you have and instead go with something like floated columns.

    This might look like this::

    <?php
$days_of_week = array(
    '1' => 'Sunday',
    '2' => 'Monday',
    // etc.
);
?>
<div style="overflow: auto;">
<?php foreach ($calendar as $day_index => $classes) { ?>
    <div style="width: 150px; margin: 5px; float: left;">
        <div style="margin: auto;"><?php echo $days_of_week[$day_index]; ?></div>
        <?php foreach ($classes as $class) {?>
            <div style="width:150px">
            <!-- class info here -->
            </div>
        <?php } ?>
    </div>
<?php } ?>
</div>
