PHP限制几点到几点

public function get_curr_time_section()
{
    $checkDayStr = date('Y-m-d ',time());
    $timeBegin1 = strtotime($checkDayStr."10:00".":00");
    $timeEnd1 = strtotime($checkDayStr."22:00".":00");

    $curr_time = time();

    if($curr_time >= $timeBegin1 && $curr_time <= $timeEnd1)
    {
        return 0;
    }

    return -1;
}
