PHPでCSV作るやつを最終的に僕はこうした

Posted at

ダウンロードもしたいし文字列としても取りたい時があるんすよね

なので2通りで返すようにしました。

  • 文字列として返す
  • ダウンロードとして出力する
  • 二次元配列で渡してあげてね。

function arr2csv($arr, $filename = false)
{
    // ダウンロード用として出力する場合は $filename を指定
    if ($filename) {
        header('Content-Type: application/octet-stream');
        header("Content-Disposition: attachment; filename=" . $filename);
        $fp = fopen('php://output', 'w');
        foreach ($arr as $line) {
            mb_convert_variables('sjis-win', 'utf-8', $line);
            fputcsv($fp, $line);
        }
        fclose($fp);
    } else {
        $out = '';
        foreach ($arr as $line) {
            $line_tmp = '"';
            $line_tmp .= implode('","', $line);
            $line_tmp .= '"' . "\n";
            mb_convert_variables('sjis-win', 'utf-8', $line_tmp);
            $out .= $line_tmp;
        }
        return $out;
    }
}
