使用现有数据在数据数组中插入对象列

Question

我有一个格式如下的现有数据数组：

Array ( [0] => Array ( [employee_id] => 14100001 [salary] => 346.35416666667 [late_duration] => 2 [undertime_duration] => 3 [cola_duration] => 0 [date] => 2019-09-09 )
     [1] => Array ( [employee_id] => 14100001 [salary] => 350 [late_duration] => 0 [undertime_duration] => 0 [cola_duration] => 0 [date] => 2019-09-10 )
     [2] => Array ( [employee_id] => 14100002 [salary] => 350 [late_duration] => 0 [undertime_duration] => 0 [cola_duration] => 0 [date] => 2019-09-09 )
     [3] => Array ( [employee_id] => 14100003 [salary] => 358.75 [late_duration] => 0 [undertime_duration] => 0 [cola_duration] => 2 [date] => 2019-09-09 )

现在我想在现有数组中插入一个数据，如下所示：

Array ( [0] => Array ( [employee_id] => 14100001 [salary] => 346.35416666667 [late_duration] => 2 [undertime_duration] => 3 [cola_duration] => 0 [date] => 2019-09-09 [calculate_id] => 1 )
[1] => Array ( [employee_id] => 14100001 [salary] => 350 [late_duration] => 0 [undertime_duration] => 0 [cola_duration] => 0 [date] => 2019-09-10 [calculate_id] => 1 )
[2] => Array ( [employee_id] => 14100002 [salary] => 350 [late_duration] => 0 [undertime_duration] => 0 [cola_duration] => 0 [date] => 2019-09-09 [calculate_id] => 1 )
[3] => Array ( [employee_id] => 14100003 [salary] => 358.75 [late_duration] => 0 [undertime_duration] => 0 [cola_duration] => 2 [date] => 2019-09-09 [calculate_id] => 1 )

这是我的代码，它 returns 错误：尝试分配属性 'calculate_id' 非对象

$calculate = $this->payroll->record_calculate_date($start_date,$end_date);

            foreach ($this->data_array as $key => $value) {
                array_push($this->data_array , $this->data_array->calculate_id = $calculate);
            }
            foreach ($$this->data_array1 as $key => $value) {
                array_push($this->data_array , $this->data_array->calculate_id = $calculate);
            }

Answer 1

您可以使用array_map

$calculate = $this->payroll->record_calculate_date($start_date,$end_date);
$f = array_map(function($v) use ($calculate){
    return $v + ["calculate_id" => $calculate];
}, $this->data_array);
$this->data_array = $f;
