Im getting a weird error I got an Undefined index even it is defined

This is the structure of my $list

Then in my PHP I did this

foreach($list as $k => $v){
  if($v['quantity-2'] > 0){
    //bla bla bla
  }
}

But I got an error Undefined index: quantity-2

What possibly was wrong?

Do all your array elements have the `'quantity-2'` key set? – ggorlen Sep 12 '18 at 00:27
Only one of your `$list` elements has a `quantity-2` key so you'll get that warning for the other two – Phil Sep 12 '18 at 00:27
@Phil so how can I fix this? should I put `if(!empty($v['quantity']) && $v['quantity-2'] > 0)` – Pure Rhymer Organization Sep 12 '18 at 00:38
@ggorlen no only one just like the above – Pure Rhymer Organization Sep 12 '18 at 00:39
Personally, I'd use the same keys in each item. I see no reason to use `quantity-n` over plain old `quantity` – Phil Sep 12 '18 at 00:42
@Phil ok thanks for the help. Should I delete this question? – Pure Rhymer Organization Sep 12 '18 at 00:43
