从 laravel 中的数组中获取特定值

Question

我正在使用 Laravel。这是我的数组 -

[{"emp_id":1,"shift":"first","status":"Present","is_unpaid":0,"start":"2018-03-21 08:00:00","结束":"2018-03-21 12:00:00"},{"emp_id":2,"shift":"first","status":"Present","is_unpaid":0,"start":"2018-03-21 08:00:00","结束":"2018-03-21 12:00:00"},{"emp_id":3,"shift":"first","status":"Present","is_unpaid":0,"start":"2018-03-21 08:00:00","结束":"2018-03-21 12:00:00"},{"emp_id":4,"shift":"first","status":"Present","is_unpaid":0,"start":"2018-03-21 08:00:00","结束":"2018-03-21 12:00:00"},{"emp_id":6,"shift":"first","status":"Present","is_unpaid":0,"start":"2018-03-21 08:00:00","结束":"2018-03-21 12:00:00"},{"emp_id":7,"shift":"first","status":"Present","is_unpaid":0,"start":"2018-03-21 08:00:00","end":"2018-03-21 12:00:00"}]

这是我的数组输出代码 -

if(empty($employee->emp_record) ){
            $sheet  = array();
        }else{
            $sheet = unserialize($employee->emp_record);
        }

        return $sheet;

我想获取 emp_id 的值并在视图中显示。当我使用return $sheet->emp_id;

试图获取非对象的属性 发生了这个错误。

Answer 1

要仅获取第一条记录，您需要使用：-

return $sheet[0]->emp_id;

但如果你想要全部，然后应用如下循环：-

foreach($sheet as $shet){
  echo $shet->emp_id;
}

输出：- https://eval.in/995586

Answer 2

你可以使用pluck()函数来获取数组的第一条记录

Answer 3

如果你想要全部，然后应用如下循环：-

    $sheet = [];
    if(!empty($employee->emp_record) ){
        foreach($sheet as $shet){
            $sheet[] = [
               "emp_id" => $shet->emp_id
               //.....rest data set
            ];
        }
    }
    return $sheet;
