为什么我的数组输出到我的mysql数据库出错？

Question

昨天有一个stackoverflow用户帮我输入了一个json文件到一个数组。它工作正常，但如果我想将数据输入数据库，输出错误。 在我尝试将其输入数据库之前，我的数据看起来像这样 - ＆gt;

Array ( [0] => Array ( [nickname] => Honk [votes] => 10 ) [1] => Array ( [nickname] => NaryX [votes] => 10 )

通过此代码获得 - ＆gt;

$json_string = $data;
$data_array = json_decode($json_string ,true);
print_r($data_array);

但是如果我尝试输入我的数据，它看起来就像这样：

这是它的代码 - ＆gt;

foreach($data_array as $data){
    $nickname = ($data['nickname']);
    $votes = ($data['votes']);

    $sql = "INSERT INTO test (nickname, votes) VALUES ('$nickname', '$votes')";

    if (!mysqli_query($connbooster, $sql)) {
        echo 'Problem to enter your data into the Database...';
    }
}

Answer 1

    <?php

    $hostname="localhost";
    $username="root";
    $password="";
    $dbname="test";

    // Create connection
    $conn = new mysqli($hostname, $username, $password, $dbname);
$data= Array('name' => 'Bloodhand [address]',  'ts.bloodhand.de [port]' => 0, 'month' => 201711, 'voters' => Array ( 0 => Array ( 'nickname' => 'Honk', 'votes' => 10 ), 1 => Array ( 'nickname' => 'NaryX' ,'votes' => 10 )));

    foreach($data['voters'] as $row) {
        $nickname = ($row['nickname']);
        $votes = ($row['votes']);

         $stmt = $conn->prepare("INSERT INTO test (nickname, votes) VALUES (?, ?)");
    $stmt->bind_param("ss", $nickname, $votes);
    $stmt->execute();


    }

这段代码对我有用。在数据库中插入应有的值。我在表格中为昵称＆amp;设置的字段类型投票是

varchar(255)

使用预准备语句

更新了查询

Answer 2

$data = file_get_contents($filename);
$json_string = $data;
$data_array = json_decode($json_string ,true);
print_r($data_array );
foreach($data_array as $row) {
    $nickname = ($row['nickname']);
    $votes = ($row['votes']);

    $sql = "INSERT INTO test (nickname, votes) VALUES ('$nickname', '$votes')";

    if (!mysqli_query($connbooster, $sql)) {
        echo 'Problem to enter your data into the Database...';

    }
}

输出 - ＆gt;

Mysql表 - ＆gt;

Answer 4

看起来像这样

Array ( [name] => Bloodhand [address] => ts.bloodhand.de [port] => 0 [month] => 201711 [voters] => Array ( [0] => Array ( [nickname] => Rici [votes] => 10 ) [1] => Array ( [nickname] => NaryX [votes] => 10 )

但你是这样写的

  

- ＆GT; `'name'=＆gt; 'Bloodhand [address]'，'ts.bloodhand.de [port]'=＆gt;

     

    

0，'month'=＆gt; 201711，'选民'=＆gt;数组（0 =＆gt;数组（'昵称'=＆gt;     'Honk'，'votes'=＆gt; 10），1 =＆gt;数组（'nickname'=＆gt;'NaryX'，'投票'     =＆GT; 10））`

  

我无法编辑这些信息，因为它们来自其他网站！
