编写背景（TP框架+数据库 dyg表 id user pwd ）
从数据库导出到Excel表格：
public function add() { $objExcel = new PHPExcel; $objWriter = PHPExcel_IOFactory::createWriter($objExcel, 'Excel5'); $objActSheet = $objExcel->getActiveSheet(0); $objActSheet->setTitle('测试'); $objActSheet->setCellValue('A1', 'id'); $objActSheet->setCellValue('B1', '账号'); $objActSheet->setCellValue('C1', '密码'); $baseRow = 2; //数据从N-1行开始往下输出 这里是避免头信息被覆盖 $explame_data = Db::name('dyg')->select(); // var_dump($explame_data);die(); foreach ($explame_data as & $lottery) { } // halt($explame_data); foreach ($explame_data as $key => $value){ $i = $baseRow + $key; // var_dump($value['user']);die(); $objExcel->getActiveSheet()->setCellValue('A' . $i, $value['id']); $objExcel->getActiveSheet()->setCellValue('B' . $i, $value['user']); $objExcel->getActiveSheet()->setCellValue('C' . $i, $value['pwd']); } $objExcel->setActiveSheetIndex(0); //4、输出 $objExcel->setActiveSheetIndex(); header('Content-Type: applicationnd.ms-excel'); // $filename = date('YmdHis');$filename header("Content-Disposition: attachment;filename=".'1'.".xlsx"); header('Cache-Control: max-age=0'); $objWriter->save('php://output'); }
从Excel表格导入到数据库：
前端：
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <title></title> <link rel="stylesheet" href=""> </head> <body> <br> <!-- 上传文件三要素 post请求 enctype 文件最大 2M --> <form action="" method="post" enctype="multipart/form-data"> 点击上传:<input type="file" name="excel"> <br/> <br/> <br/> <button>提交</button> </form> </body> </html>
后端：
public function index() { // return '<a href="' . u('add') . '">导出数据</a>'; if ( request()->isPost() ) { // $res = upload()->save('file'); $file = request()->file('excel'); $filename = $file->getRealpath(); // $filename = $res['data']['full_path']; //设置excel格式 $reader = PHPExcel_IOFactory::createReader('Excel5'); //载入excel文件 $excel = $reader->load($filename); // halt($data); // var_dump($excel);die; //读取第一张表 $sheet = $excel->getSheet(0); //获取总行数 $row_num = $sheet->getHighestRow(); //获取总列数 $col_num = $sheet->getHighestColumn(); $data = []; //数组形式获取表格数据 for ($col = 'A'; $col <= $col_num; $col++) { for ($row = 2; $row <= $row_num; $row++) { $data[$row - 2][$sheet->getCell($col . 1)->getValue()] = $sheet->getCell($col . $row)->getValue(); } } // var_dump($data);die; foreach($data as $v){ // Db::name('cs001')->where('id',$v['id']) // ->where('user',$v['user']) // ->setInc('pwd',$v['pwd']); // echo Db::getLastSql();die; dump(Db::name('cs001')->insert($v)); } }
