Error in iterating/object arrays php

Question

Good day, Im very confused why I keep on getting an undefined error whenever I tried to use '$x->split' when iterating through my array.

dd

$divs = array(3) {
  ["items"]=>
  array(4) {
    [0]=>
    object(stdClass)#247 (13) {
      ["type"]=>
      int(6)
      ["description"]=>
      NULL
      ["transactionType"]=>

        [0]=>
        object(stdClass)#246 (1) {
          ["gt_xid"]=>
          int(1)
        }
      }
    }

          int(4)
        }
      }
    }
  }
  ["accountName"]=>
  string(15) "Inventory Asset"
  ["startingBalance"]=>
  int(0)
}

the thing is Im using that kind of format when I iterate through my array on my Items. here's the way I do it.

@foreach($divs as $div)
 {{ $div['accountNam'] }}
 @foreach($div['items'] as $x)
 {{ $x->description }}
 {{ $x->date_at }}
 {{ $x->transactionType }}
 @endforeach
@endforeach

that code above works fine but when I add the 3rd inner loop

 @foreach($divs as $div)
  {{ $div['accountNam'] }}
  @foreach($div['items'] as $x)
    {{ $x->description }}
    {{ $x->date_at }}
    {{ $x->transactionType }}
       @foreach($x->split as $z)
        ----I get error here---
       @endforeach
  @endforeach
@endforeach

I get this error: Undefined property: stdClass::$split

when I tried to dd($z->split)

I get this result which means that its not empty or doesnt exist

array(1) { [0]=> object(stdClass)#246 (1) { ["gt_xid"]=> int(1) } }

Can You Please help me find the thing that I am missing here. To make it work. I already tried using $z['gt_xid'] but it gives me another error : Cannot use object of type stdClass as array .. Thank you for spending time to read this. have a nice day ahead!

Why are you prepending each and every control structure with an @? This specifically tells PHP to ignore any possible errors and warnings generated there, thus making it a LOT harder for you to debug the code. Get rid of them and you'll have a much easier time debugging. — Tularis

in your array $div['items'] is one element (index 1) without the split property.

if this may happen, you need to guard against it. I don't know the syntax you are using, but it will follow along these lines:

if (isset($x->split) :
  @foreach($x->split as $z)
    // do stuff
  @endforeach
endif;

I believe the 2nd element (key 1) of your array doesn't have a "split" value. You should test if "split" is defined (isset($x->split)) before trying to loop in it.
