将JSON编码数组中的内部数组插入到csv文件与PHP

我从DB中存储的形式值与json_encode()，我需要将这些值插入.csv文件。这里是我的代码：将JSON编码数组中的内部数组插入到csv文件与PHP

$con=mysqli_connect("localhost","db_user","db_pass","table_name"); 
if (mysqli_connect_errno()) { 
    echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
} 
mysqli_set_charset($con,"utf8"); 
$sql = $con->prepare("SELECT message FROM online_survey"); 
$sql->execute(); 
$array = []; 
foreach ($sql->get_result() as $row){ 
    $array[] = json_decode($row['message'], true); 
} 
if (!$sql) { 
    die(mysqli_error($con)); 
} 

$fp = fopen('/path/to/file.csv', 'w'); 

foreach($array as $key) { 
    fputcsv($fp, $key); 
} 

fclose($fp);

而在这个文件我正在从这种形式的所有值除了数组。例如：

Cell 1 Cell2 Cell3 Cell4 Cell5 Cell6 Cell7 OrgName Country City Position Scope Array

我需要的是让这样的：

Array 
(
[organization_name] => orgName 
[organisation_country] => Country 
[organisation_city] => City 
[organization_position] => position 
[other_1_4_text] => 
[organisation_scope] => Local 
[activity_areas] => Public finance management, Democratic participation and civil society, Urban development and management, Anti-corruption organisations and institutions, Children and youth 
)

取而代之的是：

Array 
(
[organization_name] => orgName 
[organisation_country] => Country 
[organisation_city] => City 
[organization_position] => position 
[other_1_4_text] => 
[organisation_scope] => Local 
[activity_areas] => Array 
    (
     [0] => Public finance management 
     [1] => Democratic participation and civil society 
     [2] => Urban development and management 
     [3] => Anti-corruption organisations and institutions 
     [4] => Children and youth 
    ) 
... 
)

如果您需要了解更多信息，请让我知道！

谢谢！

关于第二个'foreach'您可以转储var'var_dump（$ key）'来检查发生了什么。 –

@MichalPrzybylowicz更新！ –

检查密钥上的is_array并使用print_r（key，true）将其返回。 – Paul

你只需要破灭的阵列：

代码：（Demo）

$array=[ 
    'organization_name'=>'orgName', 
    '[organisation_country'=>'Country', 
    'organisation_city'=>'City', 
    'organization_position'=>'position', 
    'other_1_4_text'=>'', 
    'organisation_scope'=>'Local', 
    'activity_areas'=>[ 
     'Public finance management', 
     'Democratic participation and civil society', 
     'Urban development and management', 
     'Anti-corruption organisations and institutions', 
     'Children and youth' 
    ] 
]; 

foreach($array as $k=>$v){ 
    if(is_array($v)){ 
     $v=implode(', ',$v); 
    } 
    $result[$k]=$v; 
} 
var_export($result);

输出：

array (
    'organization_name' => 'orgName', 
    'organisation_country' => 'Country', 
    'organisation_city' => 'City', 
    'organization_position' => 'position', 
    'other_1_4_text' => '', 
    'organisation_scope' => 'Local', 
    'activity_areas' => 'Public finance management,Democratic participation and civil society,Urban development and management,Anti-corruption organisations and institutions,Children and youth', 
)

编辑：这将是更好地使这个修改当你通过数据库结果集循环时...

$v=json_decode($row['message'],true); 
$array[]=is_array($v)?implode(', ',$v):$v;
