Question

I have been trying to get the subgroup total of the data below using the method in the accepted answer here: how to group result in subgroups in php, but to no avail. Somebody please help.

I want this:

+---------------+-----------------+
| Type          |  Price          |
+---------------+-----------------+
| Music         |  19.99          |
| Music         |   3.99          |
| Music         |  21.55          |
| Toy           |  89.95          |
| Toy           |   3.99          |
+---------------+-----------------+

displayed as this:

Music | 45.53
Toy   | 93.94

in group and subtotal.

Answer 1

Try this…

// Get the sum
$group = array();
foreach($rows as $r){
  $group[$r->type] = $group[$r->Type] + $r->Price;
}

// Display
foreach($group as $type=>$price){
  echo "Type:".$type." Price: ".$price;
}
