Codeigniter的csv_from_result（）不能使用UTF-8字符？

Question

我有一些数据在Cyrilic中，我想用Codeigniter将它导出到.csv文件中。问题是方法csv_from_result（）会混淆那些字符。

$this->load->dbutil();
$delimiter = ",";
$newline = "\r\n";

$report_result =  $this->data_model->get_data_result();
$data['csv']    = $this->dbutil->csv_from_result($report_result, $delimiter, $newline);

在我看来，我有：

<?php
header("Content-type: application/csv-tab-delimited-table; charset=utf-8" );
header("Content-Disposition: attachment; filename=csvdata.csv" );
header("Content-Transfer-Encoding: binary" );
  echo $csv; 
?> 

输出文件包含如下的乱码：

ТеÑÑ‚ пиÑмо","54","Референц

来自ci的

csv_from_result生成没有BOM的utf-8，您可以找到差异here 所以你现在需要做的就是将“utf-8无BOM”转换为“utf-8”，你可以使用以下代码完成。

$this->load->dbutil();
$delimiter = ",";
$newline = "\r\n";

$report_result =  $this->data_model->get_data_result();
$CSV_data      = $this->dbutil->csv_from_result($report_result, $delimiter, $newline);
$CSV_data = chr(239) . chr(187) . chr(191) .$CSV_data;
$data['csv'] = $CSV_data;

我最终使用PHPExcel for Codeigniter。这就像一个魅力。

试试这个：

$this->load->dbutil();
$query = $this->db->query($sql);
$delimiter = ",";
$newline = "\r\n";

header ("Content-disposition: attachment; filename=csvoutput_" . time() . ".csv") ;
echo mb_convert_encoding($this->dbutil->csv_from_result($query, $delimiter, $newline), "ISO-8859-1", "UTF-8");
