How to use raw sql Pagination in Laravel5?

Question

This is my Controller code:

$sql = \"SELECT *,earth_distance(ll_to_earth(team.lat, team.lng), ll_to_earth(23.1215939329,113.3096030895)) AS distance FROM tea

Another option if you are trying to paginate dynamic columns that maybe you were processing calculations on for reporting is to create a sort method and pass in your array and params:

public function sort($array_of_objects, $sort_by=null, $order, $page) 
{
    $collection = collect($array_of_objects);
    if ($sort_by)
    {

        if ($order=='desc') {
            $sorted = $collection->sortBy(function($role) use ($sort_by)
            {
                return $role->{$sort_by};
            })->reverse();
        } else if ($order=='asc') {
            $sorted = $collection->sortBy(function($role) use ($sort_by)
            {
                return $role->{$sort_by};
            });
        }
    } else {
        $sorted = $collection;
    }

    $num_per_page = 20;
    if (!$page) {
        $page = 1;
    }

    $offset = ( $page - 1) * $num_per_page;
    $sorted = $sorted->splice($offset, $num_per_page);

    return  new Paginator($sorted, count($array_of_objects), $num_per_page, $page);

}
