Example analysis of custom paging effects in laravel framework

This article mainly introduces the laravel custom paging implementation code in detail, which has certain reference value. Interested friends can refer to it

For laravel paging, it comes with a paginate method. , very useful, but also has limitations.

So I wrote my own paging for this, the specific code is as follows

<?php　　
namespace ...;

use ...;
/**
 * 自定义分页类，适合少数据的查询，多数据的时候不推荐
 * Class CustomPaginate
 * @package App\Tools\Paginate
 */
class CustomPaginate
{
  /**
   * 自定义数组分页
   * @param $data = 返回结果
   * @param $page
   * @param $limit
   * @return mixed
   */
  public static function paginate($data, $page = 1, $limit = 10)
  {
    if (!is_numeric($page) || !is_numeric($limit)) {
      return false;
    }
    $count = count($data);
    $data = array_slice($data, ($page - 1) * $limit, $limit);
    return new LengthAwarePaginator($data, $count, $limit, $page);
  }

  /**
   * 参数解释 对外暴露的方法
   * @param $data = array|collection 切记只支持这两种
   * @param $page = 当前页
   * @param $limit = 每一页展示几条
   * @return array|false
   * 返回结果为数组
   * 调用实例： CustomPaginate::paginateToArray($data, $request->page, $request->limit);
   */
  public static function paginateToArray($data, $page = 1, $limit = 10)
  {
    $isValidate = self::validate($data, $page, $limit);           //验证
    if ($isValidate === false) {
      return false;
    }

    $res = self::paginate($data, $page, $limit)->toArray();         //分页数据转换为数组

    //上一页 || 下一页 => path
　　　　　　if ($res[&#39;prev_page_url&#39;] != null) {
  　　　　　　$prev_page = $page - 1;
  　　　　　　$res[&#39;prev_page_url&#39;] = Paginator::resolveCurrentPath() . "?page=" . $prev_page . "&limit=" . $limit;
　　　　　　}
　　　　　　if ($res[&#39;next_page_url&#39;] != null) {
  　　　　　　$next_page = $page + 1;
  　　　　　　$res[&#39;next_page_url&#39;] = Paginator::resolveCurrentPath() . "?page=" . $next_page . "&limit=" . $limit;
　　　　　　}
    return $res;
  }

  /**
   * 验证参数是否合法
   */
  public static function validate(&$data, &$page = 1, &$limit = 10)
  {
    $page = empty($page) ? 1 : $page;
    $limit = empty($limit) ? 10 : $limit;
    if (!is_array($data) && !$data instanceof Collection) {
      return false;//"自定义分页方法只支持数组数据和集合数据";
    }
    if (!is_numeric($page) || !is_numeric($limit)) {
      return false;//"page limit 参数只支持数字";
    }
    if ($data instanceof Collection) {
      return $data = $data->toArray();
    }
    return $data;
  }

}
