PHP Loop inside function

I have a MySql table that holds event descriptions and dates. I'm trying to create a HTML table that holds each day's events, and utilizes a function to return the data. The function I created only returns one line and not all the listings. How do I get it to display all the listings for the day?

<?php
function class_listing($classDay) {
      if ($classDay == 'Thurs'){ $timeDay = '2012-08-23';}
      else if ($classDay == 'Fri'){ $timeDay = '2012-08-24';}
      else if ($classDay == 'Sat'){ $timeDay = '2012-08-25';}
      else if ($classDay == 'Sun'){ $timeDay = '2012-08-26';}            
      
      $query = mysql_query("SELECT * FROM `classes` WHERE DATE(`date`) = '$timeDay' ORDER BY `date`");
      while($row = mysql_fetch_assoc($query))
      {

            $listing = '<tr><td valign="middle"><input name="classes'.$timeDay.'[]" type="checkbox" id="classes'.$timeDay.'[]" class="ft" value="' . $row['id'] . '"><label for="' . $row['id'] . '">' . $row['description'] . '</label></td></tr>';
      
      }
                  return $listing;
}
?>      

<table>
<tr><td>Thursday</td></tr>
<?php echo class_listing('Thurs'); ?>
<tr><td>Friday</td></tr>
<?php echo class_listing('Fri'); ?>
</table>

Add a dot before equal sign within the while loop:

     $query = mysql_query("SELECT * FROM `classes` WHERE DATE(`date`) = '$timeDay' ORDER BY `date`");
      while($row = mysql_fetch_assoc($query))
      {

            $listing .= '<tr><td valign="middle"><input name="classes'.$timeDay.'[]" type="checkbox" id="classes'.$timeDay.'[]" class="ft" value="' . $row['id'] . '"><label for="' . $row['id'] . '">' . $row['description'] . '</label></td></tr>';
     
      }

This add to the existing $listing value the new one: now you are very replaceing the value with the new one.
