将Y-m-d转换为Y年m月d日

自己编写的，不能直接套用，理解后可自行变化：

          $var=explode(' ',$res['act_starting']);

          $var1=$var[0];
          $time=explode('-',$var1);
          if($time[1]<10)
          {
            $time[1] = str_replace("0", "", $time[1]);
          }else
          {
            $time[1]=$time[1];
          }

         if($time[2]<10)
          {
             $time[2] = str_replace("0", "", $time[2]);
          }else
          {
            $time[2]=$time[2];
          }
         $json['date']=$time[0]."年".$time[1]."月".$time[2]."日";

$time = date("Y-m-d", $time);
            $var=explode(' ',$time);
            $var1=$var[0];
            $time=explode('-',$var1);
            if($time[1]<10){
            $time[1] = str_replace("0", "", $time[1]);
           }else{
                $time[1]=$time[1];
            }
            if($time[2]<10){
                $time[2] = str_replace("0", "", $time[2]);
            }else{
                $time[2]=$time[2];
            }
            $new_time  = $time[0]."年".$time[1]."月".$time[2]."日";

封装后

/**
     * 拼装年月日
     */
 
    public function rn_date($time){
        $var=explode(' ',$time);
        $var1=$var[0];
        $time=explode('-',$var1);
        if($time[1]<10){
            $time[1] = str_replace("0", "", $time[1]);
        }else{
            $time[1]=$time[1];
        }
        if($time[2]<10){
            $time[2] = str_replace("0", "", $time[2]);
        }else{
            $time[2]=$time[2];
        }
        $new_time  =$time[0]."年". $time[1]."月".$time[2]."日";
        return $new_time;
    }
