如何使用PHP创建一个保留日语字符的CSV文件? [英] How can I create a CSV file with PHP that preserves the Japanese characters?

问题描述

下面是我用于从浏览器创建和下载CSV文件的代码段.

Below is my code snippet for creating and downloading the CSV file from the browser.

$input_array[] = ['注文日時', '受注番号',];
$input_array[] = ['2015-09-30', 'INV-00001',];

    /** open raw memory as file, no need for temp files, be careful not to run out of memory thought */
    $f = fopen('php://memory', 'w');
    /** loop through array  */
    foreach ($input_array as $line) {
        /** default php csv handler **/
        fputcsv($f, $line, ',');
    }
    /** rewrind the "file" with the csv lines **/
    fseek($f, 0);

    /** modify header to be downloadable csv file **/
    header('Content-Encoding: UTF-8');
    header('Content-Type: application/csv; charset=UTF-8');
    header('Content-Disposition: attachement; filename="my_csv_file.csv";');

    /** Send file to browser for download */
    fpassthru($f);

    die();

当我打开创建/下载的CSV文件时，日语字符变成了奇怪的字符.我的代码段中还不正确的地方是什么?创建CSV文件时如何保留日语字符?

When I open the created/downloaded CSV file, the Japanese characters become the weird characters. What is not yet correct in my code snippet? How can I preserve the Japanese characters when creating the CSV file?

推荐答案

如果要强制任何程序将文件解释为UTF-8，只需在写第一行之前直接添加带有简单echo的字节顺序标记编码:

Just add a Byte Order Mark with a simple echo directly before writing the first line if you want to force any program to interpret the file as UTF-8 encoding:

$input_array[] = ['注文日時', '受注番号',];
$input_array[] = ['2015-09-30', 'INV-00001',];
echo "\xEF\xBB\xBF";/// Byte Order Mark HERE!!!!

    /** open raw memory as file, no need for temp files, be careful not to run out of memory thought */
    $f = fopen('php://memory', 'w');
    /** loop through array  */
    foreach ($input_array as $line) {
        /** default php csv handler **/
        fputcsv($f, $line, ',');
    }
    /** rewrind the "file" with the csv lines **/
    fseek($f, 0);

    /** modify header to be downloadable csv file **/
    header('Content-Encoding: UTF-8');
    header('Content-Type: application/csv; charset=UTF-8');
    header('Content-Disposition: attachement; filename="my_csv_file.csv";');

    /** Send file to browser for download */
    fpassthru($f);

    die();

或者使用Excel或Open Calc导入Unicode Character set时，也可​​以选择Unicode Character set，否则直接使用notepad/textedit/etc打开它就没有问题

Alternatively select Unicode Character set when you import it with Excel or Open Calc, otherwise opening it directly with notepad/textedit/etc there is no problem
