Question

我在我的项目中使用PHPExcel来生成来自数据库的xls数据文件。我已经下载了PHPExcel库并在我的PHP类中使用它，如下所示：

Class name : A.class.php
Path : inside a folder named "inc";
PHPExcel Lib folder : inside "inc" and relative to A.class.php


class A{

        // code stuff

        public function phpexcelgenerate()
        {
        require_once 'PHPExcel_1.7.9_doc/Classes/PHPExcel.php';
        header('Content-Type: application/vnd.ms-excel');
        header('Content-Disposition: attachment;filename="sam.xlsx"');
        header('Cache-Control: max-age=0');              
        $objPHPExcel = new PHPExcel;
        $objPHPExcel->setActiveSheetIndex(0);
        $objPHPExcel->getActiveSheet()->SetCellValue('A1', "12");

        $writer = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');  
        // This line will force the file to download    
        $writer->save();
        }
        // code stuff
        }

此代码生成xls文件但该文件完全为空。我想我在PHP类中以错误的方式包含了PHPExcel的文件。任何人都可以告诉我我在哪里做错了或者一个例子我该怎么做？

Answer 1

您需要将文件名传递给save()方法。然后读取该文件的内容并回显到浏览器。

$writer = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');  
$writer->save("excel.xls");
readfile("excel.xls");

Answer 2

首先你需要阅读文件：

    // Read the file
    $objReader = PHPExcel_IOFactory::createReader(Excel5);
    $objPHPExcel = $objReader->load($fileName);

现在从db获取数据：

    //get data
    $details = $this->main_model->get_details()->row();

然后将数据分配给正确的单元格：

    $objPHPExcel->getActiveSheet()->setCellValue('A'.$row, $i);
    $objPHPExcel->getActiveSheet()->setCellValue('B'.$row, $rec->eType);

最后写下新文件：

    header('Content-Type: application/vnd.ms-excel'); //mime type
    header('Content-Disposition: attachment;filename="'.$filename.'"'); //tell browser what's the file name
    header('Cache-Control: max-age=0'); //no cache

    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');  
    //force user to download the Excel file without writing it to server's HD
    $objWriter->save('php://output');

PHPExcel没有生成正确的xls文件
