Push操作

新增資料

public function add(){
        $this->data = [
            '作者'    =>  'tuzi',
            '年齡'    =>  '22',
            '標題'    =>  '防塔與補兵',
            '評論'    =>  [
                [
                    '序號'    => '001',
                    '內容'    => '五殺'
                ]
            ]
        ];
        $res
 
 = Db::table('document')->insert($this->data);
        if($res){
            echo "success";
        }else{
            echo "error";
        }
    }

結果

array(1) {
  [0] => array(5) {
    ["_id"] => object(MongoDB\BSON\ObjectId)#12 (1) {
      ["oid"] => string(24) "5a51f73083869e4b65549c36"
 

    }
    ["作者"] => string(4) "tuzi"
    ["年齡"] => string(2) "22"
    ["標題"] => string(15) "防塔與補兵"
    ["評論"] => array(1) {
      [0] => array(2) {
        ["序號"] => string(3) "001"
        ["內容"] => string(6) "五殺"
      }
    }
  }
}

利用push更新資料

public function update()
    {
 

        $update_data['評論'] = [
            '$push',
            [
                '序號'    =>  '002',
                '內容'    =>  '三殺'
            ]
        ];
        $update_res = Db::table('document')->where('標題','防塔與補兵')->update($update_data);
        if($update_res){
            echo "success";
        }else{
            echo "error";
        }
    }

結果

array(1) {
  [0] => array(5) {
    ["_id"] => object(MongoDB\BSON\ObjectId)#12 (1) {
      ["oid"] => string(24) "5a51f73083869e4b65549c36"
    }
    ["作者"] => string(4) "tuzi"
    ["年齡"] => string(2) "22"
    ["標題"] => string(15) "防塔與補兵"
    ["評論"] => array(2) {
      [0] => array(2) {
        ["序號"] => string(3) "001"
        ["內容"] => string(6) "五殺"
      }
      [1] => array(2) {
        ["序號"] => string(3) "002"
        ["內容"] => string(6) "三殺"
      }
    }
  }
}
