我有两张table看起来像这样

雇员人数

id
emp_id
emp_name
uan
kyc

排空

id
emp_id
doc_type
doc_number

现在我有两个模特

雇员人数

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class empPf extends Model
{
    protected $table = 'empPf';
    protected $primaryKey = 'emp_id';

     public function kyc(){

            return $this->hasMany('App\empKyc','emp_id');

        }
}

空基c

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class empKyc extends Model
{
    protected $table = 'empKyc';
    //protected $primaryKey = 'emp_id';

     public function pf(){

            return $this->belongsTo('App\empPf','emp_id');

        }
}

我正在尝试在我的控制器中执行以下代码

public function getPf(){
        Session::put('activemenu', 'emp_ss');

        $pfs = empPf::with(array('kyc'))->get();

        foreach ($pfs as  $value) {
              dd($value->kyc[0]->emp_id);
        }

    }

我收到错误
正在尝试获取非对象的属性
任何帮助都将不胜感激
