php - 接收 strtotime() 期望参数 1 是字符串，对象在 php 中给出错误

Question

当我像下面这样传递数组时，程序运行良好:

$holidays=array("2015-01-01","2015-01-05","2015-01-10");

echo getWorkingDays("2015-01-02","2015-01-09",$holidays);

但是当我像这样从数据库中提取数据时:

$holidays = DB::table('tbl_holiday')->select('holiday_date')->whereBetween('holiday_date', array('2015-01-01', '2015-01-20'))->get();

我收到此错误: strtotime() 期望参数 1 为字符串，对象给定

在我的 helpers.php 中，我有这个代码

 foreach($holidays as $holiday){

       $time_stamp=strtotime($holiday);

      //If the holiday doesn't fall in weekend
      if ($startDate <= $time_stamp && $time_stamp <= $endDate && date("N",$time_stamp) != 6 )
      $workingDays--;
}

任何帮助，将不胜感激。

只需从 $holiday 获取实际的日期字符串

$timestamp = strtotime($holiday->holiday_date);
