php把json数据导入mysql数据失败

先说下我做的原理吧：
1、先把json转换成数组；
2、在把数组中的我需要是数据提取下，组成我要是sql语句中VALUES的一部分，提取的这部分我存成一个数组；
3、由于上面提取VALUES是一个数组，我用for循环执行sql语句，但是提示i没有定义
大家看看怎么回事

回复讨论(解决方案)

现在进过群友帮助，已经发现一些问题，但是执行成功后发现添加的数据是json的最后一条数据，这个数据还有问题，数据取整了，没有小数
贴上代码

小数问题已经知道了，是数据库设置了int（10），现在设置成了decimal(10,2)就好了

for ($i=0; $i<count($value); $i++) {    $q = "INSERT INTO f_chengjiao (city_id, fang_time, taoshu, area, os_time) VALUES (1, $values[$i], NOW())";}

for ($i=0; $i     $q = "INSERT INTO f_chengjiao (city_id, fang_time, taoshu, area, os_time) VALUES (1, $values [$i], NOW())";
}

for ($i=0; $i     $q = "INSERT INTO f_chengjiao (city_id, fang_time, taoshu, area, os_time) VALUES (1, ".$values[$i].", NOW())";
}
这样当然只保存最后一条，因为$q的值会每次都被覆盖，而不是追加。你只执行了一次mysqli_query的insert操作。

改成这样，把mysqli_query写在循环体内就可以了：
for ($i=0; $i     $q = "INSERT INTO f_chengjiao (city_id, fang_time, taoshu, area, os_time) VALUES (1, ".$values[$i].", NOW())";
    $r = mysqli_query ($conn, $q) or trigger_error("Query: $q\n
MySQL Error: " . mysqli_error($conn));
    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';            
    }
}

for ($i=0; $i<count($value); $i++) {    $q = "INSERT INTO f_chengjiao (city_id, fang_time, taoshu, area, os_time) VALUES (1, $values[$i], NOW())";}

这个问题在2楼已经发现，现在根据5楼的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？？？

for ($i=0; $i     $q = "INSERT INTO f_chengjiao (city_id, fang_time, taoshu, area, os_time) VALUES (1, $values [$i], NOW())";
}

这个问题在2楼已经发现，现在根据5楼的修正后（貌似那个$values也要添加2个点点做连接符）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？？？ 

for ($i=0; $i     $q = "INSERT INTO f_chengjiao (city_id, fang_time, taoshu, area, os_time) VALUES (1, ".$values[$i].", NOW())";

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

方法都是先转为数组，然后foreach写入数据库的。

我自己也打印了下，最后提示错误

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

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？

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。
