从Sql中获取10km经纬度以下的用户

Question

实际上我是laravel的新手，我尝试从10公里纬度和经度以下的Sql中获取用户，但它抛出错误。错误是——

方法 Illuminate\Support\Collection::SQRT 不存在。

这是我的控制器代码

<?php

namespace App\Http\Controllers;

use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Routing\Controller as BaseController;
use DB;

class Controller extends BaseController
{
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;
    public function index()
    {
        $users = DB::table('users')
        ->select('id','name','phone','latitude','longitude')
        ->get()
        ->SQRT("POW(69.1 * (latitude - 24.900110), 2) +
        POW(69.1 * (67.099760 - longitude) * COS(latitude / 57.3), 2)) AS distance")
        ->having("distance < 25")
        ->orderBy("distance");

         return view('userview', compact('users'));

    }
}

Answer 1

你可以试试这个——

$users = DB::table('users')
          ->select(DB::raw('id,name,phone, SQRT(POW(69.1 * (latitude - 24.900110), 2) + POW(69.1 * (67.099760 -longitude) * COS(latitude / 57.3), 2)) AS distance'))
          ->havingRaw('distance < 25')
          ->OrderBy('distance')
          ->get();
