どのようにJsonをCSVにPHPで変換する

Question

こんにちは私はcssファイルに通常のものよりdifferrent配列構造を持つJSONファイルを変換しようとしています。私はそれをcsvファイルに変換する解決策を見つけようとしていましたが、解決策を見つけることはできません。

<?php 
    $jsondata = '[{ 
     "accession_number_original": "2012.11.45", 
     "author_birth_date": [ 
      "1932" 
     ], 
     "author_date": [ 
      "1932" 
     ], 
     "author_death_date": [ 
      "" 
     ], 
     "author_description": [ 
      "American" 
     ], 
     "author_display": [ 
      "Day yon" 
     ], 
     "author_names_first": [ 
      "Day" 
     ], 
     "author_names_last": [ 
      "yon" 
     ], 
     "author_names_middle": [ 
      "" 
     ], 
     "image_height": "12 1/2", 
     "image_width": "18 1/4", 
     "jp2_image_url": "", 
     "location_physical_location": "Art Gallery", 
     "location_shelf_locator": "Unknown", 
     "master_image_url": "", 
     "note_provenance": "Gift of Gary Ginsberg and Susanna Aaron", 
     "object_date": "1963/2010", 
     "object_depth": "", 
     "object_height": "", 
     "object_width": "", 
     "origin_datecreated_end": "1963", 
     "origin_datecreated_start": "1963", 
     "physical_description_extent": [ 
      "12 1/2 x 18 1/4" 
     ], 
     "physical_description_material": [ 
      "Gelatin silver print" 
     ], 
     "physical_description_technique": [ 
      "Gelatin silver print" 
     ], 
     "pid": "bdr:123456", 
     "title": "As Demonstrators" 
     }]'; 

    $jsonDecoded = json_decode($jsondata); 
    print_r('<pre>'); 
    print_r($jsonDecoded); 
    print_r('</pre>'); 
    $fh = fopen('fileout.csv', 'w'); 
    if (is_array($jsonDecoded)){ 
     print_r('<-------- line variable output-------->'); 
     foreach($jsonDecoded as $line){ 
      print_r('<pre>'); print_r($line); print_r('</pre>'); 
     print_r('<-------- data variable output-------->'); 
     if (is_array($line)||is_object($line)){ 
      foreach($line as $data){ 
      fputcsv($fp,$data); 
      } 
      } 
     } 
     } 
    } 

    fclose($fh); 
    print_r('Converted Successfully'); 
?> 

私はstackoverflowで同様の質問のほとんどを調べてみましたが、どれも私の種類の配列を持っていないので、あまり役に立ちません。

私は、単一のforeachを使用している場合、私は文字列の変換にエラー配列を取得していますがとアレイは、csvファイルに代わり、実際のデータの値として印刷されていませんでした。

私は2つのforeachを使用している場合は、私が（エラーfputcsvを取得していますが）、パラメータ2が

指定された配列の文字列であることを期待PHPExcelライブラリーに使用

私はコメントで述べたように、最初のステップは、配列値の世話をすることですので、各行が値を持っている必要があり、配列がある場合（それだけで、あなたが提供する形式でカウント変換2つの値で、最初のものだけがcsvに渡されます）。

あなたの修正されたソースコード：実行後の

$jsonDecoded = json_decode($jsondata, true); // add true, will handle as associative array  
print_r('<pre>'); 
print_r($jsonDecoded); 
print_r('</pre>'); 
$fh = fopen('fileout.csv', 'w'); 
if (is_array($jsonDecoded)) { 
    print_r('<-------- line variable output-------->'); 
    foreach ($jsonDecoded as $line) { 
    // with this foreach, if value is array, replace it with first array value 
    foreach ($line as $key => $value) { 
     if (is_array($value)) { 
      $line[$key] = $value[0]; 
     } 
    } 
    print_r('<pre>'); print_r($line); print_r('</pre>'); 
    // no need for foreach, as fputcsv expects array, which we already have 
    if (is_array($line)) { 
     fputcsv($fh,$line); 
    } 
    } 
} 
fclose($fh); 
print_r('Converted Successfully'); 

スクリプトの出力：

[output of your print_r($jsonDecoded);] 

<-------- line variable output--------> 

Array 
(
    [accession_number_original] => 2012.11.45 
    [author_birth_date] => 1932

    [author_death_date] => 
    [author_description] => American

を次のようにのvar_dumpや復号化されたJSONのしますprint_r結果がありますそれは私のjsonファイルをExcelシートに変換するのに役立ちます。 https://github.com/PHPOffice/PHPExcel

   $keyName=array(); 
       $i=0; 
       $current_data=file_get_contents($dir.$excelFileLocation,true); 
       $excelFile=fopen($dir."ExcelTojson.xls","w+"); 
       $array_data=json_decode($current_data,true); 
       foreach($array_data as $jsonValue) 
       { 
        foreach($jsonValue as $key => $value) 
        { 
         if($i==0) 
         { 
          $keyName[$i]=$key; 
          $i++; 
         } 
         else 
         { 
          $check=0; 
          for($j=0;$j<count($keyName);$j++) 
          { 
           if($keyName[$j]==$key) 
           { 
            $check=1; 
            break; 
           } 
          } 
          if($check==0) 
          { 
           $keyName[$i]=$key; 
           $i++; 
          } 
         } 
        } 
       } 
       $excelSheet = PHPExcel_IOFactory::load($dir."ExcelTojson.xls"); 
       $excelSheet->setActiveSheetIndex(0); 
       $ascii=65; 
       for($i=0;$i<count($keyName);$i++) 
       { 
        $excelSheet->getActiveSheet()->setCellValue(chr($ascii)."1",stripslashes($keyName[$i])); 
        $ascii+=1; 
       } 
       $cellValue=2; 
       foreach($array_data as $jsonValue) 
       { 
        $ascii=65; 
        foreach($jsonValue as $key => $value) 
        { 
         $excelSheet->getActiveSheet()->setCellValue(chr($ascii).$cellValue,stripslashes($value)); 
         $ascii+=1; 
        } 
        $cellValue+=1; 
       } 

       $filename="ExcelTojson.xls"; 
       header('Content-Type: application/vnd.ms-excel'); 
       header('Content-Disposition: attachment;filename="'.$filename.'"'); 
       header('Cache-Control: max-age=0'); 
       $objWriter = PHPExcel_IOFactory::createWriter($excelSheet, 'Excel5'); 
       $objWriter->save('php://output');
