php - MySQL列数据有断线时Excel数据很奇怪

Question

我使用标头机制通过下载概念将 MySQL 列数据导出到 excel 文件中。问题是，如果一个列text的datatype数据包含breaklines类似enumeration的数据，那么 csv 文件很奇怪：枚举的数据被放置在 excel 文件的不同行中。那么如何让数据放在一个单元格内呢？

这是下载的代码：

function downloadFile($outPut, $fileName){

        $filesize = strlen($outPut);

        header("Pragma: public");
        header("Expires: 0");
        header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
        header("Content-type: text/enriched");
        header("Content-length: $filesize");
        header("Content-disposition: attachement; filename=$fileName");

        ob_clean();
        flush();

        print($outPut);

        exit();
    }

Answer 1

My first suggestion would be to ensure that each of the fields you are exporting are within double quotes if they are not already, this will save a lot of formatting issues e.g. with commas within a field etc. If you are still having problems I would suggest trying to replace the newline characters with something that you will interpret as a new line (or just as space). Try this in your sql (around the field that ,ay have newline characters:

REPLACE(your_column_name,'\n',' ')

一种肮脏的方法是使用“\r\n”作为以CSV文件结尾的实际行；和一个简单的“\n”作为单元格内的分隔线，确保引用包含分隔线的任何单元格值。

$fh = fopen('test.csv', 'w+');
fwrite($fh, "sep=\t" . "\r\n");
fwrite($fh, 'A' ."\t" . 'B' . "\t" . 'C' . "\r\n");
fwrite($fh, 'D' ."\t" . "\"E\nF\nG\"" . "\t" . 'H' . "\r\n");
fclose($fh);

此示例在单元格之间使用制表符分隔符；并在单元格 B2 中显示三行值

或使用 fputcsv()

$fh = fopen('test2.csv', 'w+');
fwrite($fh, "sep=\t" . PHP_EOL);
fputcsv($fh, array('A', 'B', 'C'), "\t");
fputcsv($fh, array('D', "E\nF\nG", 'H'), "\t");
fclose($fh);
