Short Version of question:
I received Cannot use object of type stdClass as array
when using Query Builder, but works fine with Eloquent. How I solve that issue?
Long Version of question:
When I using method 1 there is a error.
Error : Cannot use object of type stdClass as array (This gives for view foreach start line)
But when I using method 2 there is no error.
I wanted to know why it return error when I using method 2. How I correct it?
Method 01 (In Controller)
$parents = DB::table('stuparents');
$parents = $parents->orderBy('first_name');
$parents = $parents->get();
Method 02 (In Controller)
$parents = StuParents::orderBy('first_name');
$parents = $parents->get();
In View
@foreach($parents as $student)
//Code
@endforeach
This is the var_dump of both methods.
Method 01

I'm guessing that in the code where you have something like
{{ $student['something'] }}
is where the error is actually being caused.The database query builder method
get()
returns an instance ofIlluminate\Support\Collection
where each entry is astdClass
and not an array. To access columns, use properties not indexes.To quote the documentation:
The get method returns an Illuminate\Support\Collection containing the results where each result is an instance of the PHP StdClass object. You may access each column's value by accessing the column as a property of the object.
