Question

I have a query which returns the below from joining two tables:

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

My problem is how do I group the products by type, so that it displays a single product type and total price for each product type? For example:

Music | 45.53
Toy   | 93.94

and so on.

Answer 1

Got it at last.

// 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;
}
