使用utf-8编码的csv导出数据出现乱码php

Question

因此，我有此页面将数据库转换为csv。

转换设置为utf8时，数据库也设置为utf8。

问题是在excel中打开csv文件后，数据出现乱码。 看起来像这样：

KN01001     | 荳陦帙,admin@listmaster.com"  | List Master          |                |
KN01002     | 譌ｭ譚ｾ                        | information@e877.jp  |   Info Master  |

但是当我尝试将文件拖到记事本中时，数据还可以，它显示：

"KN01001","荳陦帙","admin@listmaster.com","List Master"
"KN01002","譌ｭ譚ｾ蝣","information@e877.jp","Info Master"

我怎样才能使其在excel中看起来还不错？

更新：

我尝试按照建议添加PHPExcel，但仍然给我同样的乱码输出。

我在这里包括了我的代码，也许有人可以帮助编辑代码。

控制器：

public function bg_convcsv($sendTo, $searchName, $searchAdd, $prefKey, $searchKey, $withEmail, $withTel, $withFax) {

        $sendTo = rawurldecode($sendTo);

        $headerArray = array("foreign key", "prefecture_id", "industry_id", "offset", "name", "email", "tel", "fax", "address", "url", "flexible_1", "flexible_2", "flexible_3", "flexible_4", "flexible_5", "sequence", "del_flg", "create_date", "create_user", "update_date", "update_user", "site_name");

        // Header
        $header = str_replace(",", "", $headerArray);

        $datas = implode(',', $header) . "\r\n";

        // Body
        $limit = 50000;
        $start = 0;
        do {
            $list = $this->user_model->get_users($searchName, $searchAdd, $prefKey, $searchKey, $withEmail, $withTel, $withFax, $limit, $start);
            foreach($list as $body)
            {
                $email = //some codes to clean email
                $url = // some codes to clean url
                $datas .= '"' .$body["id"].'"'.",".'"' .$body["prefecture_id"].'"'.",".'"' .$body["industry_id"].'"'.",".'"' .$body["offset"].'"'.",".'"' .$body["name"].'"'.",".'"' .$email .'"'.

            }

            $start += $limit;
        }while(count($list) > 0);

        $fileName = "listmaster_".date('YmdHis').".csv";
        $csv_handler = fopen ('/var/www/citest/csv/'.$fileName,'w');
        fwrite ($csv_handler,$datas);
        fclose ($csv_handler);
}

public function download() {

            log_message('debug', 'starting download.');
            $file = $_GET['file'];
            $filePath = '/var/www/citest/csv/'.$file;

            if(!$file){ // file does not exist
                die('file not found');
            } else {
                header('HTTP/1.1 200 OK');
                header('Cache-Control: no-cache, must-revalidate');
                header("Pragma: no-cache");
                header("Expires: 0");
                header("Content-type: text/csv; charset=UTF-8");
                header("Content-Disposition: attachment; filename=$file");

                // read the file from disk
                log_message('debug', 'reading file.');
                readfile($filePath);
                log_message('debug', 'reading file done');
            }
    }

这是我如何使用PHPExcel做到的

Answer 1

如@luhuiya所述，您可以使用phpexcel来获得正确的格式。

假设您已经使用composer安装了phpexcel。

这是一个工作示例：

<?php

require_once __DIR__ . '/vendor/autoload.php';

/*
You query your data into an array here
$data = ...
*/

$data = [
    [ 'KN01001', '荳陦帙', 'admin@listmaster.com', 'List Master', '' ],
    [ 'KN01002', '譌ｭ譚ｾ', 'information@e877.jp', 'Info Master', '' ],
];

$phpXls = new PHPExcel();

// Fill worksheet from values in array
$phpXls->getActiveSheet()->fromArray($data, null, 'A1');

// Work on PHPExcel object, set worksheet metadata
// Change the ... parts according to your needs
$phpXls->getProperties()->setCreator("...")
    ->setLastModifiedBy("...")
    ->setTitle("...")
    ->setSubject("...")
    ->setDescription("...")
    ->setKeywords("...");

$phpXls->getActiveSheet()->setTitle('...');

// I saw in your examlpe data, that you can have long strings in some columns
// Therefore You can widen the excel columns in order to be readable at full length.
// Get Excel column range and dynamically resize columns
$highestColumn = $phpXls->getActiveSheet()->getHighestColumn();
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
foreach (range(0, $highestColumnIndex) as $columnIndex) {
    $phpXls->getActiveSheet()->getColumnDimensionByColumn($columnIndex)->setAutoSize(true);
}

 // Set active sheet index to the first sheet, so Excel opens this as the first sheet
$phpXls->setActiveSheetIndex(0);

// Save Excel 2007 file
$xlsWriter = PHPExcel_IOFactory::createWriter($phpXls, 'Excel2007');

$xlsWriter->save('your_data.xlsx');
