laravel 框架给数组分页

//Get current page form url e.g. &page=6
        $currentPage = LengthAwarePaginator::resolveCurrentPage();

$currentPage -= 1;

//Create a new Laravel collection from the array data
        $collection = new Collection($log_data['content']);

//Define how many items we want to be visible in each page
        $perPage = 10;

//Slice the collection to get the items to display in current page
        $currentPageSearchResults = $collection->slice($currentPage * $perPage, $perPage)->all();

//Create our paginator and pass it to the view
        $paginatedSearchResults= new LengthAwarePaginator($currentPageSearchResults, count($collection), $perPage);

$url = url('admin/statistics/index');

$paginatedSearchResults = $paginatedSearchResults->setPath($url);
