PhpSpreadsheet 导出图片到 Excel

之前使用的是PHPExcel来做PHP程序的数据导出，但是ThinkPHP5版本就改成了PhpSpreadsheet，文档因为是英文的所以看不太懂，今天解决的是PhpSpreadsheet 导出图片到 Excel。

代码1：

      /**

* [export 导出数据]

*/

public function export() {

//查询数据

$data = $this->model->field('id,user_id,thumb,content,create_time')->with(['user'])->order('create_time desc')->select();

//处理数据

if(!empty($data)){

foreach ($data as $key => $value) {

if(!empty($value['thumb'])){

$data[$key]['thumb'] = json_decode($value['thumb'], true);

}

//ip

/*if(isset($value['ip']) && !empty($value['ip'])){

$data[$key]['ip'] = getIpInfo($value['ip']);

}*/

}

}

//创建一个新的excel文档

$newExcel = new \PhpOffice\PhpSpreadsheet\Spreadsheet();

//获取当前操作sheet的对象

        $objSheet = $newExcel->getActiveSheet();

        //设置当前sheet的标题

        $objSheet->setTitle('意见反馈');

        //设置宽度为true,不然太窄了

        $newExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);

        $newExcel->getActiveSheet()->getColumnDimension('B')->setWidth(20);

        $newExcel->getActiveSheet()->getColumnDimension('C')->setWidth(20);

        $newExcel->getActiveSheet()->getColumnDimension('D')->setWidth(40);

        $newExcel->getActiveSheet()->getColumnDimension('E')->setWidth(30);

        //设置第一栏的标题

        $objSheet->setCellValue('A1', 'ID')

                 ->setCellValue('B1', '用户')

                 ->setCellValue('C1', '图片')

                 ->setCellValue('D1', '内容')

                 ->setCellValue('E1', '时间');

        //第二行起，每一行的值,setCellValueExplicit是用来导出文本格式的。

        //->setCellValueExplicit('C' . $key, $val['admin_password']PHPExcel_Cell_DataType::TYPE_STRING),可以用来导出数字不变格式

        if(!empty($data)){

        foreach ($data as $key => $val) {

            $key = $key + 2;

            //设置第行高度

        $newExcel->getActiveSheet()->getRowDimension($key)->setRowHeight(65);

        //设置行值

            $objSheet->setCellValue('A' . $key, $val['id'])

                     ->setCellValue('B' . $key, $val['username'])

                     //->setCellValue('C' . $key, $val['thumb'][0])

                     ->setCellValue('D' . $key, $val['content'])

                     ->setCellValue('E' . $key, $val['create_time']);

            //处理图片

            if(!empty($val['thumb'][0])){

            $thumb = str_replace(request()->domain(), '.', $val['thumb'][0]);

            $drawing[$key] = new \PhpOffice\PhpSpreadsheet\Worksheet\Drawing();

                $drawing[$key]->setName('图片');

                $drawing[$key]->setDescription('图片');

                $drawing[$key]->setPath($thumb);

                $drawing[$key]->setWidth(80);

            }

        }

        } else {

        $this->error('暂无数据');

        }

        //导出

        $filename = '意见反馈';

        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');

        header("Content-Disposition: attachment;filename=" . $filename . date('Y-m-d') . '.' . strtolower($format));

        header('Cache-Control: max-age=0');

        $objWriter = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($newExcel, $format);

        return $objWriter->save('php://output');

        //通过php保存在本地的时候需要用到

        //$objWriter->save($dir.'/demo.xlsx');

        //以下为需要用到IE时候设置
