Grouping using while loop


Recommended Posts

This is example of my record:



  1. year quanitity name
  2. 2012 10 john
  3. 2012 20 mark
  4. 2013 30 david
  5. 2013 40 alex
  6. 2014 50 stacy
while (!$report->EOF){
if(is_null($year) || $year <> $report->fields['year']) {
$year = $report->fields['year'];
<tr><td align="center" colspan="2" >Year : </td><td><?=$year ?></td></tr>
<tr><td align="center" colspan="2" >Quantity : </td><td><?=$report->fields['quanitity'] ?></td></tr>

How to do so the result goes like this

1) group by years

2) total quantity for each year

year : 2012
name : john quantity : 10
name : mark quantity : 20

Total : 30


year : 2013
name : david quantity : 30
name : alex quantity : 40
Total : 70

if there is a selection option for year to show up the following you want.

$query_list("SELECT year, quantity, name from BDNAME WHERE year = '$selected_year'");
$query_result = mysql_query($query_list);

thin apply from guru suggestion and others.
