Question

我在将文件feom CSV转换为XLSX格式时遇到问题：

的index.php

<?php
if (!isset($_FILES["file"]))
{
?>
<html>
    <body>
        <h1>Convert CSV to XLSX</h1>
        <form action="index.php" method="post" enctype="multipart/form-data">
            <input type="file" name="file"/>
            <input type="submit"/>
        </form>
    </body>
</html>
<?php
    exit;
}

//obtain PHPExcel from http://phpexcel.codeplex.com
require_once('Classes\PHPExcel.php');
require_once('CSVToExcelConverter.php');

if ($_FILES["file"]["error"] > 0)
{
    echo "Error: " . $_FILES["file"]["error"];
    exit;
}

try
{
    header('Content-type: application/ms-excel');
    header('Content-Disposition: attachment; filename='.'example.xlsx');

    CSVToExcelConverter::convert($_FILES['file']['tmp_name'], 'php://output');
} catch(Exception $e) {
    echo $e->getMessage();
}

CSVToExcelConverter.php

class CSVToExcelConverter
{
    /**

    public static function convert($csv_file, $xls_file, $csv_enc=null) {
        //set cache
        $cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_to_phpTemp;
        PHPExcel_Settings::setCacheStorageMethod($cacheMethod);

        //open csv file
        $objReader = new PHPExcel_Reader_CSV();
        if ($csv_enc != null)
            $objReader->setInputEncoding($csv_enc);
        $objPHPExcel = $objReader->load($csv_file);
        $in_sheet = $objPHPExcel->getActiveSheet();

        //open excel file
        $objPHPExcel = new PHPExcel();
        $out_sheet = $objPHPExcel->getActiveSheet();

        //row index start from 1
        $row_index = 0;
        foreach ($in_sheet->getRowIterator() as $row) {
            $row_index++;
            $cellIterator = $row->getCellIterator();
            $cellIterator->setIterateOnlyExistingCells(false);

            //column index start from 0
            $column_index = -1;
            foreach ($cellIterator as $cell) {
                $column_index++;
                $out_sheet->setCellValueByColumnAndRow($column_index, $row_index, $cell->getValue());
            }
        }

        //write excel file
        $objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
        $objWriter->save($xls_file);
    }
}

CSV文件格式：CSV file opened with Excel

xlsx file I get after conversion

Basicaly我想获得类似于原始csv文件的输出，但是在xmlx格式中，该怎么做？

用于在PHPExcel中读取CSV文件的“默认”分隔符是逗号（,）。您的CSV文件使用的不是逗号 - 可能是标签（"\t"），这也常用于此类文件。）

如果值不是逗号（我们无法从MS Excel中查看的文件图像中得知），那么您必须在加载前明确告诉PHPExcel该分隔符。

e.g。

$objReader->setDelimiter("\t");
