Laravel 5 JSON Foreach不起作用

Question

I am trying to get data from from foreach loop, and i am pulling that data from database. When I try to "foreach" it says Invalid argument supplied for foreach()

@php
$extras = json_decode($product->extras);
@endphp

@foreach($extras as $key)

print_r($key);
@endforeach

When i do it on local, it works, but on laravel it won't.

Also, when i write OUTSIDE of foreach

{{$extras[0][0]}}

it works.. any suggestions?

Answer 1

This was the answer.. no logic but works..

$extras = json_decode($product->extras);
if (is_array($extras) || is_object($extras)){
    foreach ($extras as $extra){  

    }
}
