PHP が json データを mysql データにインポートできない

まず、私が行うことの原理について説明します:
1. まず json を配列に変換します。
2. 配列内のデータを抽出した後、抽出された部分を SQL ステートメントの VALUES の一部として形成します。配列として;
3. 上記で抽出した VALUES は配列であるため、for ループを使用して SQL ステートメントを実行しましたが、i が定義されていないというメッセージが表示されました
何が起こっているのか見てみましょう

ここで、グループのヘルプを入力していくつかの問題を見つけましたが、正常に実行された後、追加されたデータは、このデータにまだ問題があることがわかりました。は四捨五入されており、小数点はありません

修正后发现数据不能全部添加，数据一共有30条，但是添加到数据的时候，数据就到了9月16号那天就结束了（数据库本身有一点数据），自增的id也正好是30，这是什么情况？？？  同时我想问下，还有什么方法可以降json数据导入数据库，由于json数据太多了，所以希望有一个批量的方法

我在重新添加了下数据，数据还是到了id=30的时候不添加了，但是提示都添加成功了，到数据库中看数据添加不全
你看下截图

看看你现在的程序

你的json不是只有30????？
怎??有31

    if (mysqli_affected_rows($conn) == 1) {
        echo '这条数据已经添加成功';
    } else {
        echo '程序发生错误，请重新添加';            
    }
??要放在每一次mysqli_query之後呢。

这个是独立的文件，上面2个引入文件是数据库文件，不打紧

    }
??要放在每一次mysqli_query之後呢。

前面17条数据是以前写的测试数据，从id=18开始就是导入数据，每次都是到了id=30就结束导入了，这时候数据都没有前面添加完全

你的程序几经修改了，你不给我看到你现在的程序的话，我如何告诉你怎样调试？

config 不加载，那 MYSQL 常量是在哪里定义的？

config已经打开了

<?phprequire ('inc/config.php');require (MYSQL);//连接数据库$data ='[{"date":"2014-09-06","num":151,"area":18017.24},{"date":"2014-09-07","num":103,"area":11703.9},{"date":"2014-09-08","num":66,"area":7378.92},{"date":"2014-09-09","num":192,"area":22160.96},{"date":"2014-09-10","num":183,"area":22059.72},{"date":"2014-09-11","num":184,"area":21212.68},{"date":"2014-09-12","num":119,"area":13960.93},{"date":"2014-09-13","num":0,"area":0},{"date":"2014-09-14","num":43,"area":5056.19},{"date":"2014-09-15","num":121,"area":12867.43},{"date":"2014-09-16","num":93,"area":8755.81},{"date":"2014-09-17","num":80,"area":9035.69},{"date":"2014-09-18","num":158,"area":17613.12},{"date":"2014-09-19","num":112,"area":12180.37},{"date":"2014-09-20","num":74,"area":8614.02},{"date":"2014-09-21","num":95,"area":10305.27},{"date":"2014-09-22","num":258,"area":30695.9},{"date":"2014-09-23","num":155,"area":17457.88},{"date":"2014-09-24","num":148,"area":16792.02},{"date":"2014-09-25","num":167,"area":20203.15},{"date":"2014-09-26","num":174,"area":20055.03},{"date":"2014-09-27","num":138,"area":15927.18},{"date":"2014-09-28","num":175,"area":19372.63},{"date":"2014-09-29","num":277,"area":30226.38},{"date":"2014-09-30","num":311,"area":33082.01},{"date":"2014-10-01","num":88,"area":9456.33},{"date":"2014-10-02","num":92,"area":9384.07},{"date":"2014-10-03","num":70,"area":7780.39},{"date":"2014-10-04","num":71,"area":7620.61},{"date":"2014-10-05","num":44,"area":4672.24}]';$array = json_decode($data, true);//print_r ($array);$values = array();  foreach ($array as $k => $v) {	//echo "('" . $k .

虽然添加成功，但是还是到id=30的时候就不添加后面的数据了（数据实际到了9月17号就结束了）

截图中有30个添加成功

你总是再添加，并没有哪里再删除，数据都加了好几遍了
你也不看看？

30个成功我看到了，但是数据添加不全，你可以看看我在11楼的截图
整个数据是id=1到id=17是我以前写程序添加的测试数据，并不在json内，json数据是从id=18开始，添加到id=30就结束了，但是这时候的json在id=30以后的数据数据库里面没有

我知道那里错了，谢谢提醒，原来代码没有错，是我数据库设置的问题。给分结贴，谢谢大家的耐心解答。

不是还有下一页吗？
