I'm not going to modify your query, but instead use a collection, which will transform the data after the get() method.
$PlanDetail = PalnCategory::select('id','title')
->with('Categorys','PlanDetails')
->get()
->groupBy('categorys.0.id')
->values()
->map(function($item){
$sub = collect($item)->map(function($item){
$return = collect($item)->forget(['categorys', 'plan_details'])->all();
$return['plans'] = $item['plan_details'];
return $return;
})->toArray();
$category = $item[0]['categorys'][0];
$category['categorys'] = $sub;
return $category;
});
return response()->json($PlanDetail);
Output :
[
{
"id": 1,
"title": "category 1",
"categorys": [
{
"id": 5,
"subcategor_name": "regular",
"plans": [
{
"id": 6,
"details": "plan1 reg"
}
]
},
{
"id": 6,
"subcategor_name": "primum",
"plans": [
{
"id": 7,
"details": "plan2 reg2"
}
]
}
]
},
{
"id": 2,
"title": "category 2",
"categorys": [
{
"id": 7,
"subcategor_name": "cat2 reg",
"plans": [
{
"id": 8,
"details": "plan1"
}
]
}
]
}
]
