【tp5.1】composer安裝PHPExcel以及導入\導出Excel

一、安裝PHPExcel

1.下載：PHPExcel  https://github.com/PHPOffice/PHPExcel

2.解壓后：Classes文件夾改名為PHPExcel 

3.把文件夾PHPExcel 放到根目錄vendor文件夾下

 

二、控制器

1.調用PHPExcel

use PHPExcel_IOFactory;
use PHPExcel;

 

 

2.導入

//    導入每日流水
    public function posImport(){
        header("content-type:text/html;charset=utf-8");
        //上傳excel文件
        $file = request()->file('excel');
        //將文件保存到public/uploads目錄下面
        $info = $file->validate(['size'=>1048576,'ext'=>'xls,xlsx'])->move( './uploads');
        if($info){
            //獲取上傳到后台的文件名
            $fileName = $info->getSaveName();
            //獲取文件路徑
            $filePath = Env::get('root_path').'public'.DIRECTORY_SEPARATOR.'uploads'.DIRECTORY_SEPARATOR.$fileName;
            //獲取文件后綴
            $suffix = $info->getExtension();
            //判斷哪種類型
            if($suffix=="xlsx"){
                $reader = \PHPExcel_IOFactory::createReader('Excel2007');
            }else{
                $reader = PHPExcel_IOFactory::createReader('Excel5');
            }
        }else{
            $this->error('文件過大或格式不正確導致上傳失敗-_-!');
        }
        //載入excel文件
        $excel = $reader->load("$filePath",$encode = 'utf-8');
        //讀取第一張表
        $sheet = $excel->getSheet(0);
        //獲取總行數
        $row_num = $sheet->getHighestRow();
        //獲取總列數
        $col_num = $sheet->getHighestColumn();
        $data = []; //數組形式獲取表格數據
        for ($i = 2; $i <= $row_num; $i ++) {
            $data[$i]['code']  = $sheet->getCell("A".$i)->getValue();
            $data[$i]['last_code']  = substr($sheet->getCell("A".$i)->getValue(),-6);
            $time = date('Y-m-d H:i',\PHPExcel_Shared_Date::ExcelToPHP($sheet->getCell("B".$i)->getValue()));
            $data[$i]['time'] = strtotime($time);
            //將數據保存到數據庫
        }
        $res = Db::name('pos_code')->insertAll($data);
        if($res){
            return redirect('/admin/pos/posCodeLog');
        }else{
            $return = [
                'code'  =>  0,
                'msg'   =>  '提交失敗，請刷新重試'
            ];
            return json($return);
        }
    }

 

3.導出

//    導出excel
    private function outExcel($data){
        $objExcel = new PHPExcel();
        $objWriter = \PHPExcel_IOFactory::createWriter($objExcel, 'Excel5');
        $objActSheet = $objExcel->getActiveSheet(0);
        $objActSheet->setTitle('領取報表');//設置excel的標題
        $objActSheet->setCellValue('A1','用戶id');
        $objActSheet->setCellValue('B1','紅包金額（元）');
        $objActSheet->setCellValue('C1','時間');
        $objActSheet->setCellValue('D1','發放狀態');

        $baseRow = 2; //數據從N-1行開始往下輸出 這里是避免頭信息被覆蓋
        foreach ( $data as $r => $d ) {
            $i = $baseRow + $r;
            $objExcel->getActiveSheet()->setCellValue('A'.$i,$d['user_id']);
            $objExcel->getActiveSheet()->setCellValue('B'.$i,$d['price']);
            $objExcel->getActiveSheet()->setCellValue('C'.$i,$d['create_time']);
            $objExcel->getActiveSheet()->setCellValue('D'.$i,$d['status'] == 1 ? '成功' : '失敗');
        }
        $objExcel->setActiveSheetIndex(0);
        //4、輸出
        $objExcel->setActiveSheetIndex();
        header('Content-Type: applicationnd.ms-excel');
        $time=date('Y-m-d');
        header("Content-Disposition: attachment;filename=領取報表$time.xls");
        header('Cache-Control: max-age=0');
        $objWriter->save('php://output');
    }
