php

需要用php将数据导出倒excel表中，用的是php的pack函数将字符打包成二进制，然后写入Excel表格文件，英文字符导入正常，现在中文字符全部乱码了，不知道哪里设置的问题呢？

下面是我的调用测试代码：

<code><?php // iconv_set_encoding('output_encoding','gbk');
    require_once("excel.php");

    $xls = new Excel('Report');

    $colors = array(
        array("red", "blue", "green", "yellow", "orange", "purple"),
        array('过以上','以','c','过','目录','f')
    );

    foreach ($colors as $key => $value) {
        $xls->home();
        foreach ($value as  $row) {
          // $xls->home();
          $xls->label($row);
          $xls->right();
           // $xls->label($row);

你中文是什么编码的啊？Excel默认是GB2312的。如果UTF-8就乱码了。

解决办法：要么转成GB2312再写进去。
要么在最后先输出BOM头

    ob_start();
    $xls->send();
    $data = "\xEF\xBB\xBF" . ob_get_clean();
    file_put_contents(__DIR__ .'/report.xls', $data);
