Receiving strtotime() expects parameter 1 to be string, object given error in php
提问by user3127109
The program works fine when I pass the array like following:
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);
But when I extract the data from database like this:
但是当我像这样从数据库中提取数据时：
$holidays = DB::table('tbl_holiday')->select('holiday_date')->whereBetween('holiday_date', array('2015-01-01', '2015-01-20'))->get();
I am getting this error: strtotime() expects parameter 1 to be string, object given
我收到此错误：strtotime() 期望参数 1 为字符串，给定的对象
In my helpers.php, I have this code
在我的 helpers.php 中，我有这个代码
foreach($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--;
}
Any help would be appreciated.
任何帮助，将不胜感激。

Just get the actual datestring from $holiday
只需从中获取实际的日期字符串 $holiday
$timestamp = strtotime($holiday->holiday_date);

Using the database query, your $holidaysvariable is an array of stdClass objects. If you want an array that contains just the holiday_datevalues, you can use the lists()method, instead of get():
使用数据库查询，您的$holidays变量是一个 stdClass 对象数组。如果你想要一个只包含holiday_date值的数组，你可以使用该lists()方法，而不是get()：
$holidays = DB::table('tbl_holiday')
->whereBetween('holiday_date', array('2015-01-01', '2015-01-20'))
->lists('holiday_date');
