ViewsWhy using unset() function cast the array to object?
Here is my code:
return ApiResponse::Json(200, '', ['categories' => $categories], 200);
And here is a screenshot of the result:
Now, I need to unset items inside categories collection based on a specific logic. So I wrote this loop:
foreach ($categories as $key => $category) {
if ($category->BusinessSubCategory->isEmpty())
unset($categories[0]);
}
return ApiResponse::Json(200, '', ['categories' => $categories], 200);
And here is my new result: (which is casted to an object)
Well .. What's wrong? How can I keep the old structure after unseting some items?

Try this:
foreach ($categories as $key => $category) {
if ($category->BusinessSubCategory->isEmpty())
unset($categories[$key]);
}
$categories = array_slice($categories->toArray(), 0, count($categories));
return ApiResponse::Json(200, '', ['categories' => $categories], 200);

The unset() method doesn't change your type.
Your 'array' is not an array but a collection.
Try:
foreach ($categories as $key => $category) {
if ($category->BusinessSubCategory->isEmpty()) {
unset($categories[0]);
break;
}
}
$categories = array_values($categories->toArray());
return ApiResponse::Json(200, '', ['categories' => $categories], 200);
Notice if you're unseting the same element you should break loop after do that.

Look like you are using relationship so you can do without loop
$category=Category::with('BusinessSubCategory')
->has('BusinessSubCategory')
->get();
or using collection
$result= $categories->filter(function ($category){
return $category->BusinessSubCategory->isNotEmpty();
});
dd($result->values()->toArray());
if $categories is not collection then use collect($categories)->filter...
