第一步：安装excel

composer.json加入一下代码，然后conposer update安装

"phpoffice/phpexcel": "^1.8"

安装之后的目录

第二步 写导出 导入代码

<?phpnamespace app\admin\controller;use app\BaseController;class Index extends BaseController{public function index(){}/** * excel 读取导入 * @return \think\response\Json|void * @throws \PHPExcel_Exception * @throws \PHPExcel_Reader_Exception */public function impExcel(){//读取excel文件$objPHPExcel = new \PHPExcel();$file_name = "C:\Users\EDZ\Downloads\智能匹配导入数据(1).xlsx";$objReader = \PHPExcel_IOFactory::createReader('Excel2007');$obj_PHPExcel = $objReader->load($file_name, $encode = 'utf-8');//加载文件内容,编码utf-8$excel_array = $obj_PHPExcel->getsheet(0)->toArray(); //转换为数组格式array_shift($excel_array);//删除第一个数组(标题);$data = [];$i = 0;foreach ($excel_array as $k => $v) {$data[$k]['id'] = $v[0];$data[$k]['name'] = $v[1];$data[$k]['image'] = $v[2];$i++;}return json($data);}/** * eccel导出 * @throws \PHPExcel_Exception * @throws \PHPExcel_Reader_Exception * @throws \PHPExcel_Writer_Exception */public function expExcel(){// 1.选取表中要输出数据$con = array(['id' => 1,'name' => '名字','image' => '头像'],['id' => 2,'name' => '名字2','image' => '头像2'],);//没有第二部//3.实例化PHPExcel类$objPHPExcel = new \PHPExcel();//4.激活当前的sheet表$objPHPExcel->setActiveSheetIndex(0);//5.设置表格头（即excel表格的第一行）$objPHPExcel->setActiveSheetIndex(0)->setCellValue('A1', 'ID')->setCellValue('B1', '姓名')->setCellValue('C1', '性别')->setCellValue('D1', '年龄')->setCellValue('E1', '电话')->setCellValue('F1', '地址')->setCellValue('G1', '详细地址');// 设置表格头水平居中$objPHPExcel->setActiveSheetIndex(0)->getStyle('A1')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objPHPExcel->setActiveSheetIndex(0)->getStyle('B1')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objPHPExcel->setActiveSheetIndex(0)->getStyle('C1')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objPHPExcel->setActiveSheetIndex(0)->getStyle('D1')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objPHPExcel->setActiveSheetIndex(0)->getStyle('E1')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objPHPExcel->setActiveSheetIndex(0)->getStyle('F1')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objPHPExcel->setActiveSheetIndex(0)->getStyle('G1')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);//设置列水平居中$objPHPExcel->setActiveSheetIndex(0)->getStyle('A')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objPHPExcel->setActiveSheetIndex(0)->getStyle('B')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objPHPExcel->setActiveSheetIndex(0)->getStyle('C')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objPHPExcel->setActiveSheetIndex(0)->getStyle('D')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objPHPExcel->setActiveSheetIndex(0)->getStyle('E')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objPHPExcel->setActiveSheetIndex(0)->getStyle('F')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);$objPHPExcel->setActiveSheetIndex(0)->getStyle('G')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);//设置单元格宽度$objPHPExcel->setActiveSheetIndex(0)->getColumnDimension('A')->setWidth(10);$objPHPExcel->setActiveSheetIndex(0)->getColumnDimension('B')->setWidth(10);$objPHPExcel->setActiveSheetIndex(0)->getColumnDimension('C')->setWidth(10);$objPHPExcel->setActiveSheetIndex(0)->getColumnDimension('D')->setWidth(10);$objPHPExcel->setActiveSheetIndex(0)->getColumnDimension('E')->setWidth(10);$objPHPExcel->setActiveSheetIndex(0)->getColumnDimension('F')->setWidth(30);$objPHPExcel->setActiveSheetIndex(0)->getColumnDimension('G')->setWidth(30);//6.循环刚取出来的数组，将数据逐一添加到excel表格。for ($i = 0; $i < count($con); $i++) {$objPHPExcel->getActiveSheet()->setCellValue('A' . ($i + 2), $con[$i]['id']);//ID$objPHPExcel->getActiveSheet()->setCellValue('B' . ($i + 2), $con[$i]['name']);//姓名$objPHPExcel->getActiveSheet()->setCellValue('C' . ($i + 2), $con[$i]['image']);//性别}//7.设置保存的Excel表格名称$filename = 'user' . date('ymd', time()) . '.xls';//8.设置当前激活的sheet表格名称$objPHPExcel->getActiveSheet()->setTitle('user');//9.设置浏览器窗口下载表格header("Content-Type: application/force-download");header("Content-Type: application/octet-stream");header("Content-Type: application/download");header('Content-Disposition:inline;filename="' . $filename . '"');//生成excel文件$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');//下载文件在浏览器窗口$objWriter->save('php://output');exit;}public function hello($name = 'ThinkPHP6'){return 'hello,' . $name;}}

注意：可能会报错、 真的是见鬼  我快晕了    别着急  看解决办法

解决直接简单粗暴 更改phpexcel包文件

continue;改成break;//再去试试就可以了

看完不懂的  随时冒泡  问我
