打开PHP创建的CSV文件

Question

I create a CSV file using fputcsv in PHP. File is created successfully and I can open the file in MacOS with no problem. (I use Numbers in MacOS). The problem is in Microsoft Excel, it shows all row as merged one single column.

I set delimiter as ";" in the code.

When I check for Language and Regional Settings as told in Microsoft documentation, the delimiter is also ";".

What should I also check for? Thank you.

Answer 1

Well this header will allow the csv format to displayed properly.

 header('Content-Encoding: UTF-8');
    header('Content-type: text/csv; charset=UTF-8');
    header('Content-Disposition: attachment; filename=filename.csv');
    echo "\xEF\xBB\xBF";

You can use this header

Answer 2

The following method seems to do the trick for me. Microsoft Excel opens it perfectly.

$filePath = '/home/user/';
$filename = 'test.csv';

$df = fopen($filePath.$filename, 'w');
fprintf($df, chr(0xEF).chr(0xBB).chr(0xBF));
fputcsv($df, $dataColumns);
foreach ($dataArray as $dataRow) {
    fputcsv($df, $dataRow);
}
fclose($df);

// Output csv
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename='.$filename);
header("Cache-Control: no-store, no-cache");
readfile($filePath.$filename);

Notes

• the line fprintf($df, chr(0xEF).chr(0xBB).chr(0xBF)); writes file header for correct encoding.
• You can use the third parameter of fputcsv(...) to set the delimiter.
