PHP Two Foreach Loops Multiply values from each loop on each iteration

Question

I have these two loops

          foreach($decode_pricing->items as $items=>$item) {
              $cost .= number_format($item->pricing[0]->cost, 2);
          }

          foreach($qty_ea as $ea) {
              $ff .= $ea;
          }

top foreach outputs

44.8244.8244.82

formatted

44.82
44.82
44.82

bottom foreach outputs

formatted

1
2
1

How can I multiply the top value with the bottom value on each iteration of the loop?

The output I want is

44.82
89.64
44.82

Can you show us the structure of your input qty_ea and $decode_pricing->items. var_dump them in order to allow us to see the structure. Another question, you inputs are always the same size? — olibiaz

what do you mean by same size? The quantity and dollar amount will be different on each transaction. — Mike

You can do something like this

 foreach($decode_pricing->items as $key => $item) {
          $cost .= $qty_ea[$key] * number_format($item->pricing[0]->cost, 2);
      }

Assuming your both of your arrays are Numeric.
