Put 2 objects inside the object - php

Question

I'm writing some queries and receiving the $help_articles:
[
{
"id": 10,
"title": "Creative Agency Creation",
"sub_title": "Learn how to create creative agency and setup information and users",
"featured_image": image.jpg",
"content": "[{some content}]",
},
{
"id": 12,
"title": "Create New User",
"sub_title": "Instruction to create new user",
"featured_image": "56095569_step_3.jpg",
"content": "[{some_content}]",
}
]
Another query is returning $related_articles
[
{
"title": "Creative Agency Creation",
"slug": "creative-agency-creation"
},
{
"title": "Create New User",
"slug": "create-new-user"
},
]
I need 2 put this 2 objects in 1 like this:
{
"all_articles": [
{
"id": 10,
"title": "Creative Agency Creation",
"sub_title": "Learn how to create creative agency and setup information and users",
"featured_image": image.jpg",
"content": "[{some content}]",
},
{
"id": 12,
"title": "Create New User",
"sub_title": "Instruction to create new user",
"featured_image": "56095569_step_3.jpg",
"content": "[{some_content}]",
}
],
"related_articles": [
{
"title": "Creative Agency Creation",
"slug": "creative-agency-creation"
},
{
"title": "Create New User",
"slug": "create-new-user"
},
]
}
I'm making the following:
$final = new \stdClass();
$final=$help_articles;
$final['related_articles'] = $related_articles;
return response()->json($final);
But I didn't get the required result.
Please advice, what I'm doing wrong and how to fix this

Answer 1

#Cbroe, thanks a lot, it's helped.
The solution was simple:
$final = [
'all_articles' => $help_articles,
'related_articles' => $related_articles
];
return response()->json($final);

Answer 2

What about compact()? It was like
$all_articles = []; //some array
$related_articles = []: //some data
return response()->json(compact(['all_articles', 'related_articles']));

Answer 3

Try this it will work in your case.
$final = new stdClass();
$final->all_articles = $all_articles;
$final->related_articles = $related_articles;
return response()->json($final);
