Php 将json转换为csv将返回数组、数组

我试图将json文件转换为csv，但csv文件中只打印文本“array，array”。我猜这是因为返回了多个数组，但作为noob，我不知道如何修复这个问题

 <?php

 $jsonString = file_get_contents("data.json");

//Decode the JSON and convert it into an associative array.
$jsonDecoded = json_decode($jsonString, true);
$jsonDecoded = $jsonDecoded;


//Give our CSV file a name.
$csvFileName = 'example.csv';

//Open file pointer.
$fp = fopen($csvFileName, 'w');

//Loop through the associative array.
foreach($jsonDecoded as $row){
    //Write the row to the CSV file.
    fputcsv($fp, $row);
}

//Finally, close the file pointer.
fclose($fp);


print $jsonDecoded;
echo json_last_error_msg();

?>

您只需参考

“数据”

键即可

foreach($jsonDecoded['data'] as $row){ ...

您可以看到

print\r（$jsondecodded）的问题

$JSONDECODE=$JSONDECODE是…您可以通过
print\r（$jsondecodded）查看问题的可能副本
$JSONDECODE=$JSONDECODE是…可能重复的
 $jsonString = file_get_contents("data.json");

//Decode the JSON and convert it into an associative array.
$jsonDecoded = json_decode($jsonString, true);
$list= $jsonDecoded;

file = new SplFileObject('example.csv', 'w');

foreach ($list as $fields) {
    $file->fputcsv($fields);
}
