Laravel 5.2 - Change Data Format get from Eloquent

Question

I have a model like this-

$feature_project = FeatureProject::select('feature_id')
                       ->where('project_id', $project->id)
                       ->get();

And if I return it, I am getting a output like this-

[
  {
    "feature_id": 2
  },
  {
    "feature_id": 4
  },
  {
    "feature_id": 9
  }
]

But I want t output like this-

[2,4,9]

So I need to convert the output.

But I am not finding a way without using for-each loop (make a temp array, push all elements to that array from current array with a for-each loop).

But I think there is more smart way than that in Laravel to do that.

I think Laravel Collection is used for this purpose.

You can call pluck() method on the query builder.

$feature_project = FeatureProject::select('feature_id')
                                        ->where('project_id', $project->id)
                                        ->pluck('feature_id'); // [2,4,9]

Alternatively, you can use PHP's array_column() function for raw arrays. http://php.net/manual/en/function.array-column.php
