【问题描述】：

我尝试使用带有 Cakephp 2.5 的 PHPExcel 库将数据导出到 Excel 文件。我的代码：

<?php

App::import('Vendor', 'PHPExcel', array('file' => 'PHPExcel'.DS.'PHPExcel.php'));
App::import('Vendor', 'PHPExcel_IOFactory', array('file' => 'PHPExcel'.DS.'PHPExcel'.DS.'IOFactory.php'));
App::import('Vendor', 'PHPExcel_IOFactory', array('file' => 'PHPExcel'.DS.'PHPExcel'.DS.'Style.php'));

class LeadUploadController extends AppController {

    public function exel_download($emp_id='')
    {
        $this->autoRender = false;
        $this-> layout='ajax';

        $objPHPExcel = new PHPExcel();
        $serialnumber=0;
        $tmparray =array("Sr.Number","Employee ID","Employee Name");
        $sheet =array($tmparray);
        $tmparray =array();
        $serialnumber = $serialnumber + 1;
        array_push($tmparray,$serialnumber);
        $employeelogin = 'aa';
        array_push($tmparray,$employeelogin);
        $employeename = 'bb';
        array_push($tmparray,$employeename);   
        array_push($sheet,$tmparray);
        header('Content-type: application/vnd.ms-excel');
        header('Content-Disposition: attachment; filename="file.xlsx"');
        $worksheet = $objPHPExcel->getActiveSheet();
        foreach($sheet as $row => $columns) {
        foreach($columns as $column => $data) {
        $worksheet->setCellValueByColumnAndRow($column, $row + 1, $data);
        }
        }
        $objPHPExcel->getActiveSheet()->getStyle("A1:I1")->getFont()->setBold(true);
        $objPHPExcel->setActiveSheetIndex(0);
        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
        $objWriter->save(str_replace('.php', '.xlsx', __FILE__));
    }
}

问题是下载的 Excel 文件不包含任何数据，它完全空白并出现错误“无法打开文件，因为文件格式或扩展名无效”。不知道这些代码有什么问题。

【问题讨论】：

您可以尝试将输出作为 txt 文件而不是 xlsx 发送。生成都一样，只是改变文件名。确保调试已打开。然后，您应该在文本编辑器（例如记事本）中打开它发送的内容，然后您可以查看它以查看输出是否正确，或者其中是否嵌入了有用的调试通知。

【解决方案1】：

以下代码应该适用于xls 扩展。

    $objPHPExcel = new PHPExcel();
    $serialnumber=0;
    $tmparray =array("Sr.Number","Employee ID","Employee Name");
    $sheet =array($tmparray);
    $tmparray =array();
    $serialnumber = $serialnumber + 1;
    array_push($tmparray,$serialnumber);
    $employeelogin = 'aa';
    array_push($tmparray,$employeelogin);
    $employeename = 'bb';
    array_push($tmparray,$employeename);   
    array_push($sheet,$tmparray);
    header('Content-type: application/vnd.ms-excel');
    header('Content-Disposition: attachment; filename="file.xls"');
    $worksheet = $objPHPExcel->getActiveSheet();
    foreach($sheet as $row => $columns) {
        foreach($columns as $column => $data) {
            $worksheet->setCellValueByColumnAndRow($column, $row + 1, $data);
        }
    }
    $objPHPExcel->getActiveSheet()->getStyle("A1:I1")->getFont()->setBold(true);
    $objPHPExcel->setActiveSheetIndex(0);
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
    $objWriter->save('php://output');
