thinkphp3.2.3 excel导出,下载文件,包含图片

关于导出后出错的问题

我遇到了文件损坏,经过百度,大神说是缓冲区的问题,在导出函数的第一行加上

ob_end_clean();

thinkphp3.2和phpexcel导出带生成图片完美案例

第一步：下载PHPEXCEL文件（这个可以百度下载）




第二步：解压这个文件，把这里全部的文件复制到 ThinkPHP/Library/Org/Util
这个文件夹下面（如图所示）, 并把 PHPExcel.php 这个文件改名为 PHPExcel.class.php



第三步：如何使用




通过上面的代码，已经成功导出一下excel文件

生成excel的代码如下和上面图片类似

public function imgexcel(){
　　　　 ob_end_clean();
        import("Org.Util.PHPExcel");
        $excel = new PHPExcel();
        $excel->getProperties()->setCreator("JAMES")
                            ->setLastModifiedBy("JAMES")
                            ->setTitle("zltrans")
                            ->setSubject("Dorder")
                            ->setDescription("Dorder List")
                            ->setKeywords("Dorder")
                            ->setCategory("Test result file");
        $excel->setActiveSheetIndex(0)
            ->setCellValue("A1","hello")
            ->setCellValue("A3","龙龙")
            ->setCellValue("B2","你好")
            ->setCellValue("B4","世界");

        import("Org.Util.PHPExcel.IOFactory");
        $excelWriter = PHPExcel_IOFactory::createWriter($excel,'Excel2007');
//转码文件名,防止汉字乱码
        $filename = iconv("utf-8","gb2312","guagua龙.xlsx");
        $excelWriter->save($filename);//使用下载方法一的时候注释
        $this->force_download($filename);//使用下载方法一的时候注释
}

下载方法一:

header('Content-Type: application/vnd.ms-excel');
        header("Content-Disposition: attachment;filename="$filename"");//文件名
        header('Cache-Control: max-age=0');
        $objWriter = PHPExcel_IOFactory::createWriter($excel, 'Excel2007');
        $objWriter->save('php://output'); //文件通过浏览器下载

 下载方法二:

导出到了服务器上,如果需要下载到客户端的话如下:

//下面两个是下载需要的函数
public function force_download($filename)
    {
        if ($filename == ''){
            return FALSE;
        }
        if (FALSE === strpos($filename, '.')){
            return FALSE;
        }
        $x = explode('.', $filename);
        $extension = end($x);
        $mimes =$this->getMimes();
        // Set a default mime if we can't find it
        if ( ! isset($mimes[$extension])){
            $mime = 'application/octet-stream';
        }else{
            $mime = (is_array($mimes[$extension])) ? $mimes[$extension][0] : $mimes[$extension];
        }
        // Generate the server headers
        if (strpos($_SERVER['HTTP_USER_AGENT'], "MSIE") !== FALSE)
        {
            header('Content-Type: "'.$mime.'"');
            header('Content-Disposition: attachment; filename="'.$filename.'"');
            header('Expires: 0');
            header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
            header("Content-Transfer-Encoding: binary");
            header('Pragma: public');
            header("Content-Length: ".filesize($filename));
        }
        else
        {
            header('Content-Type: "'.$mime.'"');
            header('Content-Disposition: attachment; filename="'.$filename.'"');
            header("Content-Transfer-Encoding: binary");
            header('Expires: 0');
            header('Pragma: no-cache');
            header("Content-Length: ".filesize($filename));
        }
        readfile($filename);
    }

 下面是导出excel带图片的代码

这个代码的使用环境是图片全部是网络图片,需要下载下来,然后在将图片放进excel,如果是本地图片可以直接169行参数写完整的图片路径即可

以下代码是写在thingphp3.2的function.php里面的

  1 /**
