fetch associated duplicates results


Recommended Posts

Hi, i dont know where im going wrong here, but when i get the results for the query it duplicates the results with a new instance for each associated result?

where i would expect:

1st line:     start time > job > Bus etc...

2ndline:   1st customer name > address etc....

3rd line:   2nd customer name > address blah blah


i actually get 


1st line:     start time > job > Bus etc...

2ndline:   1st customer name > address etc....

3rdline:   start time > job > Bus etc...

4thline:   1st customer name > address etc....

$result = mysqli_query($con,"SELECT mrbs_participants.username,mrbs_entry.room_id, mrbs_entry.id, mrbs_entry.start_time, mrbs_entry.name, mrbs_entry.fee, mrbs_users.display_name, mrbs_users.address, mrbs_users.town, mrbs_users.postcode, mrbs_users.home_number FROM mrbs_entry LEFT JOIN mrbs_participants ON mrbs_entry.id = mrbs_participants.entry_id LEFT JOIN mrbs_users ON mrbs_participants.username = mrbs_users.name where from_unixtime(start_time, '%Y-%m-%d') = CURDATE() AND driver = 'Tony'");
/////////////////////start of job list/////////////////////
echo '<div id="Tony">';
echo '<br><p><h1>Tony.</h1></p><br>';
echo "<table border='1'>
<th>Start Time</th>
<th>Start Mileage</th>
<th>End Mileage</th>
$lastEntry = null;
while($row = mysqli_fetch_array($result))
  if (is_null($lastEntry) || $lastEntry != $row['id'])
echo "<tr>";
echo "<td>" . date('l d F Y H:i',$row["start_time"]-=3600) . "</td>";
echo "<td>" . $row['name'] . "</td>";
echo "<td>" . date($row["room_id"] +=1) . "</td>";
echo "<td>" . $row["fee"] . "</td>";
echo "<td>" . $row["Start Mileage"] . "</td>";
echo "<td>" . $row["End Mileage"] . "</td>";
echo "<td>" . $row["Passengers"] . "</td>";
echo "</tr>";
$lastEntry = $row['id']; }
   {echo "<span>" . $row["username"] . "</span>";}
if (!is_null($lastEntry)) 

    echo "</td></tr>";
echo "</table>";

  ////// end of customer list////////////

When you dump $row at the top of your loop, can you see the problem?
