MYSQL PHP Order By Date and individual group results for each date

I tried to find a solution to my problem, but I'm not quite sure what I’m looking for, so I’m out of luck.

I have a simple MySQL database with one table called "actions". In this table, I have fields for "start_date", "activity_description" and "activity_location".

I am trying to execute a MySQL query using PHP and display the results in ascending order of date, but all actions that drop out on the same date, separated by a header.

For example, I am trying to achieve the following.

2012-05-03

  • Take your dog for a walk.
  • A park

  • Go out for dinner
  • Small italian restaurant

2012-05-04

  • Get car service
  • Johns Auto and Mechanical

2012-05-05

  • Shop in stores.


  • Go
  • MegaPlex

  • .

, MQSQL :

$result = mysql_query("SELECT * FROM activities ORDER BY start_date ASC")

, , :

while($row = mysql_fetch_array($result))
{
echo 
  '<strong>' .  
  $row['start_date'] . 
  '</strong>' .
  '<ul><li>' . 
  $row['activity_description'] .
  '</li><li>' .     
  $row['activity_location'] . 
  '</li></ul>'; 
 }

try this might work:

$last_date = '';    
while($row = mysql_fetch_array($result))
    {
$display_date = ($last_date == $row['start_date']) ? '' : $row['start_date'];
    echo 
      '<strong>' .  
      $display_date . 
      '</strong>' .
      '<ul><li>' . 
      $row['activity_description'] .
      '</li><li>' .     
      $row['activity_location'] . 
      '</li></ul>'; 
$last_date = $row['start_date'];     
}

    $result[$row['start_date']][] = array($row['activity_description'], $row['activity_location']);

         '</li><li>' .

Put the date in the $ date variable and check each line if the date has changed.

$date = "";while($row = mysql_fetch_array($result)){
if ($date != $row['start_date'])
{
    $date = $row['start_date'];
    echo '<strong>'.$row['start_date'].'</strong>';
}
echo '<ul><li>'.$row['activity_description'].'</li><li>'.$row['activity_location'].'</li></ul>';

}

Try something like this (I missed a few style additions to make it a little clearer):

$yourdate = '';
$output = '';

while($row = mysql_fetch_array($result)) {
    if ($yourdate != $row['start_date']) {
        $output .= $row['start_date'];
    }

    $output .= '<ul><li>' . 
       $row['activity_description'] .
      '</li><li>' .     
      $row['activity_location'] . 
      '</li></ul>';
}

echo $output;
