我有两个包含json格式数据的文件：

New_data.json

      "v": [1234,1234,1234,1234,1234,1234,1234]
    }
  }
}]

基本上，我需要使用 new_data.json 中的最新数据更新 old_data.json 文件。

但是这些新数据应该位于 old_data.json 的开头，所以最终的json文件“ data_updated.json ”如下所示：

[{"AUDCAD" : { 
               "MN": {
                           //New_data |  Old_data
                       "t":[1435708800,1234,1234,1234,1234],
                       "o":[0.9652,1234,1234,1234,1234],
                       "h":[0.9653,1234,1234,1234,1234],
                       "l":[0.94,1234,1234,1234,1234],
                       "c":[0.9508,1234,1234,1234,1234],
                       "v":[4040241,1234,1234,1234,1234]
                     }
              },
   ....
 }]

要执行此操作，我在array_unshift的每个位置使用array，我的代码如下所示：

//First I open the json files using jsonDB.class.php of Straussn's
$new_data = $db->selectAll("new_data.json");
$old_data = $db->selectAll("old_data.json");

foreach ($new_data as $j) {
    array_unshift($old_data[0]["AUDCAD"]["M1"]['t'], $j["AUDCAD"]["M1"]["t"][0]);
    array_unshift($old_data[0]["AUDCAD"]["M1"]['o'], $j["AUDCAD"]["M1"]["o"][0]);
    array_unshift($old_data[0]["AUDCAD"]["M1"]['h'], $j["AUDCAD"]["M1"]["h"][0]);
    array_unshift($old_data[0]["AUDCAD"]["M1"]['l'], $j["AUDCAD"]["M1"]["l"][0]);
    array_unshift($old_data[0]["AUDCAD"]["M1"]['c'], $j["AUDCAD"]["M1"]["c"][0]);
    array_unshift($old_data[0]["AUDCAD"]["M1"]['v'], $j["AUDCAD"]["M1"]["v"][0]);

//I repeat this spagheti code for each symbol "AUD / ..." each time "M1,M5, M15..." and each data "t, o, h, l, c, v". 
//I must repeat this 200000 times.
}

我知道执行这个简单的操作完全是荒谬的写/重复+200000行代码，但我是编程的初学者，我找不到实际的方法来执行这个动作。 也许你可以帮助我做些什么来优化这个动作，学习更多并改进我的代码。

感谢大家的时间。

你试过吗，

 b = driver.find_elements_by_css_selector('input.there.are.several.classes.input-sm')

或者

array_merge_recursive( $newdata, $olddata );

首先是鸡肉或鸡蛋，我是懒惰想出来的。

array_slice可能会帮到你。

array_splice( $data, 0, 0, $newData);

这将更新$data并在{0}位置插入$newData。
