How to remove a key from an object not array in laravel - php

Question

I get data from database using this query
$cats = Category::with(['cat_trans' => function($q) use($lang){
$q->where('lang_code', $lang);
}])->with(['cat_prod' => function($query) use ($lang,$currency){
$query->with(['pro_trans' => function ($q) use ($lang){
$q->where('lang_code', $lang);
}]);
////////////
$query->with(['pro_price' => function ($q) use ($currency){
$q->with('currency_code')->where('cur_code', $currency);
}]);
///////////
}])->whereHas('account_type', function($qr) use ($account_type){
$qr->where('account_type_id', $account_type);
})->get();
I'm trying to remove the empty objects from the result, when I tried this I got the following response
{
"1": {
"id": 1,
"parent_id": null,
"order": 1,
"name": "Moblie",
"slug": "mobile-1",
"created_at": "2018-07-08 09:41:08",
"updated_at": "2018-07-08 10:30:17",
"cat_trans": [
{
"id": 1,
"category_id": 1,
"field": "title",
"value": "Mobile",
"lang_code": "en",
"created_at": "2018-07-08 09:51:59",
"updated_at": "2018-07-08 09:51:59"
},
{
"id": 2,
"category_id": 1,
"field": "desc",
"value": "smart",
"lang_code": "en",
"created_at": "2018-07-08 09:52:41",
"updated_at": "2018-07-08 09:52:41"
},
{
"id": 12,
"category_id": 1,
"field": "slug",
"value": "mobile-1",
"lang_code": "en",
"created_at": null,
"updated_at": null
}
],
}
}
I want to remove the key "1" from all the responses.
I used unset to get this value using this code
foreach ($cats as $k) {
if (count($k->cat_prod) == 0) {
unset($cats[$va]);
}
$va++;
}
Then I tried using array_values but it displays that I can just use array_values on an array not an object.

Answer 1

You can remove key "1" by simply doing
array_values((array)$cats)
You were receiving error for this function like "Can Only be used on array" was due to Laravel Query returns object , so you just need to do type conversion on it.

Answer 2

$cats->toArray() if u need either to convert object to array or convert with some specific conditions

Answer 3

Your output looks like JSON so you can do this to eliminate the 1:
json_encode( $cats->{1} );

Answer 4

You can use laravel simple method mapWithKeys()
$cats = $cats->mapWithKeys(function ($item) {
return $item > 2;
});
$keyed->all();
