我有一个非常简单的东西，它只是输出一些CSV格式的东西，但它必须是UTF-8。我在TextEdit或TextMate或Dreamweaver中打开这个文件，它会正确地显示UTF-8字符，但如果我在Excel中打开它，它会做这种愚蠢的íÄ之类的事情。下面是我在我的文档头部得到的内容:
header("content-type:application/csv;charset=UTF-8");
header("Content-Disposition:attachment;filename=\"CHS.csv\"");
这一切似乎都达到了预期的效果，除了Excel (Mac, 2008)不想正确地导入它。Excel里没有“以UTF-8格式打开”之类的选项，所以……我有点烦了。
我似乎在任何地方都找不到任何明确的解决方案，尽管很多人都有同样的问题。我看到的最多的事情是包括BOM，但我不知道如何做到这一点。正如你所看到的，我只是回显这些数据，我没有写入任何文件。如果我需要，我可以这样做，我只是没有因为在这一点上似乎不需要这样做。任何帮助吗?
更新:我尝试将BOM作为回显包(“CCC”，0xef, 0xbb, 0xbf);这是我刚刚从一个试图检测BOM的网站上找到的。但Excel只是在导入时将这三个字符附加到第一个单元格，仍然会把特殊字符弄乱。
**This is 100% works fine in excel for both Windows7,8,10 and also All Mac OS.**
//Fix issues in excel that are not displaying characters containing diacritics, cyrillic letters, Greek letter and currency symbols.
function generateCSVFile($filename, $headings, $data) {
//Use tab as field separator
$newTab = "\t";
$newLine = "\n";
$fputcsv = count($headings) ? '"'. implode('"'.$newTab.'"', $headings).'"'.$newLine : '';
// Loop over the * to export
if (! empty($data)) {
foreach($data as $item) {
$fputcsv .= '"'. implode('"'.$newTab.'"', $item).'"'.$newLine;
}
}
//Convert CSV to UTF-16
$encoded_csv = mb_convert_encoding($fputcsv, 'UTF-16LE', 'UTF-8');
// Output CSV-specific headers
header('Set-Cookie: fileDownload=true; path=/'); //This cookie is needed in order to trigger the success window.
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$filename.csv\";" );
header("Content-Transfer-Encoding: binary");
header('Content-Length: '. strlen($encoded_csv));
echo chr(255) . chr(254) . $encoded_csv; //php array convert to csv/excel
exit;
}
我刚刚处理了同样的问题，并提出了两个解决方案。
Use the PHPExcel class as suggested by bpeterson76.
Using this class generates the most widely compatible file, I was able to generate a file from UTF-8 encoded data that opened fine in Excel 2008 Mac, Excel 2007 Windows, and Google Docs.
The biggest problem with using PHPExcel is that it's slow and uses a lot of memory, which isn't an issue for reasonably sized files, but if your Excel/CSV file has hundreds or thousands of rows, this library becomes unusable.
Here is a PHP method that will take some TSV data and output an Excel file to the browser, note that it uses the Excel5 Writer, which means the file should be compatible with older versions of Excel, but I no longer have access to any, so I cannot test them.
function excel_export($tsv_data, $filename) {
$export_data = preg_split("/\n/", $tsv_data);
foreach($export_data as &$row) {
$row = preg_split("/\t/", $row);
}
include("includes/PHPExcel.php");
include('includes/PHPExcel/Writer/Excel5.php');
$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$sheet = $objPHPExcel->getActiveSheet();
$row = '1';
$col = "A";
foreach($export_data as $row_cells) {
if(!is_array($row_cells)) { continue; }
foreach($row_cells as $cell) {
$sheet->setCellValue($col.$row, $cell);
$col++;
}
$row += 1;
$col = "A";
}
$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$filename.'.xls"');
header('Cache-Control: max-age=0');
$objWriter->save('php://output');
exit;
}
Because of the efficiency issues with PHPExcel, I also had to figure out how to generate a UTF-8 & Excel compatible CSV or TSV file.
The best I could come up with was a file that was compatible with Excel 2008 Mac, and Excel 2007 PC, but not Google Docs, which is good enough for my application.
I found the solution here, specifically, this answer, but you should also read the accepted answer as it explains the problem.
Here is the PHP code I used, note that I am using tsv data (tabs as delimiters instead of commas):
header ( 'HTTP/1.1 200 OK' );
header ( 'Date: ' . date ( 'D M j G:i:s T Y' ) );
header ( 'Last-Modified: ' . date ( 'D M j G:i:s T Y' ) );
header ( 'Content-Type: application/vnd.ms-excel') ;
header ( 'Content-Disposition: attachment;filename=export.csv' );
print chr(255) . chr(254) . mb_convert_encoding($tsv_data, 'UTF-16LE', 'UTF-8');
exit;
Add:
fprintf($file, chr(0xEF).chr(0xBB).chr(0xBF));
Or:
fprintf($file, "\xEF\xBB\xBF");
在将任何内容写入CSV文件之前。
例子:
<?php
$file = fopen( "file.csv", "w");
fprintf( $file, "\xEF\xBB\xBF");
fputcsv( $file, ["english", 122, "বাংলা"]);
fclose($file);
