Use merge() and filter() to merging two collections and filter the data based on a condition.
public function index()
{
$basicData = collect([
['id' => 1, 'title' => 'First title'],
['id' => 2, 'title' => 'Second title'],
['id' => 3, 'title' => 'Third title'],
]);
$data = collect([
['id' => 1, 'status' => 1],
['id' => 2, 'status' => 0],
['id' => 3, 'status' => 1],
]);
$mergedData = $basicData->map(function ($item) use ($data) {
return $extraData = $item + $data->firstWhere('id', $item['id']);
})->filter(function ($item) {
return $item['status'] == 1;
});
dd($mergedData);
