$select=$this->datas->query("selectdata01fromds_meters_320114102ORDERBYiddesclimit24");$result=$select->result();$datas=array();foreach($resultas$row){$datas[]=$row;}//var_dump($datas);echojson_encode($datas);以上是我查詢數(shù)據(jù)庫得出的json，這個json結(jié)果輸出后是這樣的格式：[{"data01":"20.90"},{"data01":"20.90"},{"data01":"21.00"},{"data01":"20.90"},{"data01":"21.00"},{"data01":"21.00"},{"data01":"21.00"},{"data01":"21.00"},{"data01":"21.00"},{"data01":"21.00"},{"data01":"20.90"},{"data01":"21.00"},{"data01":"21.00"},{"data01":"21.00"},{"data01":"21.00"},{"data01":"21.00"},{"data01":"21.00"},{"data01":"21.00"},{"data01":"21.00"},{"data01":"20.90"},{"data01":"20.90"},{"data01":"20.90"},{"data01":"20.90"},{"data01":"20.90"}]可是這個數(shù)據(jù)不是我想要的，我要把這個json變成這樣的格式：[20.90,20.90,21.00,20.90,21.00,21.00....]請問如何實現(xiàn)呢？謝謝
