Codeigniter + PHPExcel庫問題

Question

我使用PHPExcel庫如圖所示這里 。 但是，tt無法正常工作。 當我搜索時，有人建議將PHPEXcel_IOFactory替換為IOFactory 。 它會下載文件，但無法打開。 有什么建議么？

這是我的圖書館代碼：

Excel.php

require_once APPPATH.'/third_party/PHPExcel.php';
class Excel extends PHPExcel
{
    public function __construct()
    {
        parent::__construct();
    }
}

這是控制器代碼：

        #load our new PHPExcel library
        $this->load->library('excel');

        $data = $this->report_model->get_all_report_product_info();
        $filename = "Output";

        # Set the active Excel worksheet to sheet 0 
        $this->excel->setActiveSheetIndex(0);

        $row_count = 2;
        foreach ($data as $row) {
            $this->excel->getActiveSheet()->setCellValue('A' . $row_count, $row->product_name);
            $this->excel->getActiveSheet()->setCellValue('B' . $row_count, $row->product_sku);
            $this->excel->getActiveSheet()->setCellValue('C' . $row_count, $row->customer_name);
            $this->excel->getActiveSheet()->setCellValue('D' . $row_count, $row->site_url);
            $row_count++;
        }

        header('Content-Type: application/vnd.ms-excel');
        header('Content-Disposition: attachment;filename="' . $filename . '.xlsx"');
        header('Cache-Control: max-age=0');

        // Instantiate a Writer to create an OfficeOpenXML Excel .xlsx file
        $objWriter = IOFactory::createWriter($this->excel, 'Excel5');

        // Write the Excel file to filename
        $objWriter->save('php://output');

Answer 1

$objWriter = IOFactory::createWriter($this->excel, 'Excel5');

“ Excel5”是舊的電子表格格式（用於.XLS文件）。 如果要創建XLSX文件，則需要使用“ Excel2007”。
