Question

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文件中没有任何数据，它完全空白，并显示错误“由于文件格式或扩展名无效，无法打开文件”。不知道这些代码有什么问题。
