按月份过滤，格式为“Ymd”

我有一个date格式Y-m-d。如何按月过滤？我用诸如此类的数字指定了月份January = 1, February = 2。

public function scopegetmonthleavereport($query,$payroll_employee_id,$month)
{

         $query->join('tbl_payroll_leave_employee_v2','tbl_payroll_leave_schedulev2.payroll_leave_employee_id','=','tbl_payroll_leave_employee_v2.payroll_leave_employee_id')
         ->join("tbl_payroll_employee_basic","tbl_payroll_leave_employee_v2.payroll_employee_id","=","tbl_payroll_employee_basic.payroll_employee_id")
         ->join("tbl_payroll_leave_tempv2","tbl_payroll_leave_employee_v2.payroll_leave_temp_id","=","tbl_payroll_leave_tempv2.payroll_leave_temp_id")
         ->select(DB::raw('tbl_payroll_employee_basic.payroll_employee_id , tbl_payroll_leave_schedulev2.payroll_schedule_leave, tbl_payroll_employee_basic.payroll_employee_display_name, tbl_payroll_leave_schedulev2.payroll_leave_temp_with_pay, tbl_payroll_leave_tempv2.payroll_leave_type_id, tbl_payroll_leave_employee_v2.payroll_leave_employee_id, tbl_payroll_leave_schedulev2.consume, tbl_payroll_leave_employee_v2.payroll_leave_temp_hours, sum(tbl_payroll_leave_schedulev2.consume) as total_leave_consume, (tbl_payroll_leave_employee_v2.payroll_leave_temp_hours - sum(tbl_payroll_leave_schedulev2.consume)) as remaining_leave'))
         ->groupBy('tbl_payroll_leave_employee_v2.payroll_leave_temp_id')
         ->where('tbl_payroll_leave_schedulev2.payroll_leave_schedule_archived',0)
         ->where('tbl_payroll_leave_employee_v2.payroll_employee_id', $payroll_employee_id)
         ->whereBetween('tbl_payroll_leave_schedulev2.payroll_schedule_leave', $date);  //where i want to put the date


    return $query;
}
