PHP使用 xlswriter 高效导出数据

1、安装扩展：参考文档

2、php中使用：

 		set_time_limit(0);
        ini_set('memory_limit','128M');
        $data = []; //此处假设有百万条数据
     
        $sheetNum = ceil(count($data) / 50000);
        $config = [
            'path' => ROOT_PATH // xlsx文件保存路径
        ];
        $excel  = new \Vtiful\Kernel\Excel($config);
        $sheet = 1;
        for ($i = 1;$i<=$sheetNum;$i++){
            if($i > 1){
                $excel->addSheet("sheet{$i}");
            }
            $filePath = $excel->fileName('test01.xlsx', "sheet{$i}")
                ->header(['id','unionid','mobile','nickname','avatarurl','city','province','country_code','add_time','source_code','user_ip']);
            $n = 1;
            while ($n<= 50000){
                $v = array_shift($data);
                if(empty($v)) break;
                $excel->data([
                    [
                        $v->id,
                        $v->unionid,
                        $v->mobile,
                        $v->nickname,
                        $v->avatarurl,
                        $v->city,
                        $v->province,
                        $v->country_code,
                        $v->add_time,
                        $v->source_code,
                        $v->user_ip,
                    ]
                ]);
                $n++;
            }
            $sheet++;
        }
        $filePath = $excel->output();
        header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
        header('Content-Disposition: attachment;filename="' . $filePath . '"');
        header('Content-Length: ' . filesize($filePath));
        header('Content-Transfer-Encoding: binary');
        header('Cache-Control: must-revalidate');
        header('Cache-Control: max-age=0');
        header('Pragma: public');
        ob_clean();
        flush();
        if (copy($filePath, 'php://output') === false) {
            // Throw exception
        }
        @unlink($filePath);
