Question

こんにちは私はjsonをcsvに変換することで小さな問題があります。私はこの[{"name":"Wayne","age":28},{"name":"John","age":21},{"name":"Sara","age":24}]とその作業完璧のような別のJSON形式で試してみました

$jsonString = '{"cod":"200","calctime":0.3107,"cnt":15,"list":[{"id":2208791,"name":"Yafran","coord":{"lon":12.52859,"lat":32.06329},"main":{"temp":9.68,"temp_min":9.681,"temp_max":9.681,"pressure":961.02,"sea_level":1036.82,"grnd_level":961.02,"humidity":85},"dt":1485784982,"wind":{"speed":3.96,"deg":356.5},"rain":{"3h":0.255},"clouds":{"all":88},"weather":[{"id":500,"main":"Rain","description":"light rain","icon":"10d"}]}]}'; 

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

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

はこれを試してみてください。

$rowNr = 0; 
$prevKey = ""; 
$target = []; 

$iterator = new RecursiveArrayIterator($jsonDecoded['list'][$rowNr]); 
iterator_apply($iterator, 'traverseStructure', array($iterator,$prevKey,&$target)); 

function traverseStructure($iterator, $prevKey, &$target) { 

while ($iterator -> valid()) { 
    if ($iterator -> hasChildren()) {   
     $prevKey = $iterator->key(); 
     traverseStructure($iterator -> getChildren(), $prevKey, $target);    
    } 
    else {      
     if(isset($prevKey) && !is_int($prevKey)){    
      $row1 = $prevKey."/".$iterator->key();    
     }else{ 
      $row1 = $iterator->key(); 
     }   
     $row2 = $iterator->current();   
     $target[$row1] = $row2;   
    } 
    $iterator -> next();   
    } 
} 

fputcsv($fp, array_keys($target)); 
fputcsv($fp, array_values($target));
