在网上找了很多excel导出和导入示例，代码不是很简洁，很多出错，自己在excel方法和控制器改了下。
首先我们看下导出的HTML<a>导出</a>接着我们看下Index/excelExport 导出的PHP代码：$list = M("user")->field("id,username,password")->order("id DESC")->limit(50)->select(); $title = array('ID', '用户名', '密码'); //设置要导出excel的表头 exportExcel($list, '素材火', $title);exportExcel方法如下：function exportExcel($data, $savefile = null, $title = null, $sheetname = 'sheet1') { import("Org.Util.PHPExcel"); //若没有指定文件名则为当前时间戳 if (is_null($savefile)) { $savefile = time(); } //若指字了excel表头，则把表单追加到正文内容前面去 if (is_array($title)) { array_unshift($data, $title); } $objPHPExcel = new \PHPExcel(); //Excel内容 $head_num = count($data); foreach ($data as $k => $v) { $obj = $objPHPExcel->setActiveSheetIndex(0); $row = $k + 1; //行 $nn = 0; foreach ($v as $vv) { $col = chr(65 + $nn); //列 $obj->setCellValue($col . $row, $vv); //列,行,值 $nn++; } } //设置列头标题 for ($i = 0; $i $alpha = chr(65 + $i); $objPHPExcel->getActiveSheet()->getColumnDimension($alpha)->setAutoSize(true); //单元宽度自适应 $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setName("Candara"); //设置字体 $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setSize(12); //设置大小 $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_BLACK); //设置颜色 $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); //水平居中 $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER); //垂直居中 $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setBold(true); //加粗 } $objPHPExcel->getActiveSheet()->setTitle($sheetname); //题目 $objPHPExcel->setActiveSheetIndex(0); //设置当前的sheet header('Content-Type: application/vnd.ms-excel'); header('Content-Disposition: attachment;filename="' . $savefile . '.xls"'); //文件名称 header('Cache-Control: max-age=0'); $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007'); //Excel5 Excel2007 $objWriter->save('php://output'); }接着我们看下导入的表单：<form> <div> <label>Excel表格：</label> <input> </div> <div> <input> </div> </form>thinkphp上传Index/upload：$upload = new \Think\Upload(); // 实例化上传类 $upload->maxSize = 3145728; // 设置附件上传大小 $upload->exts = array('xls', 'xlsx'); // 设置附件上传类 $upload->savePath = '/'; // 设置附件上传目录 // 上传文件 $info = $upload->uploadOne($_FILES['file']); $filename = 'Uploads' . $info['savepath'] . $info['savename']; $exts = $info['ext']; if (!$info) {// 上传错误提示错误信息 $this->error($upload->getError()); } else {// 上传成功 $this->goods_import($filename, $exts); }goods_import导入方法：function goods_import($filename, $exts = 'xls') { //导入PHPExcel类库，因为PHPExcel没有用命名空间，只能inport导入 import("Org.Util.PHPExcel"); //创建PHPExcel对象，注意，不能少了\ $PHPExcel = new \PHPExcel(); //如果excel文件后缀名为.xls，导入这个类 if ($exts == 'xls') { import("Org.Util.PHPExcel.Reader.Excel5"); $PHPReader = new \PHPExcel_Reader_Excel5(); } else if ($exts == 'xlsx') { import("Org.Util.PHPExcel.Reader.Excel2007"); $PHPReader = new \PHPExcel_Reader_Excel2007(); } //载入文件 $PHPExcel = $PHPReader->load($filename); //获取表中的第一个工作表，如果要获取第二个，把0改为1，依次类推 $currentSheet = $PHPExcel->getSheet(0); //获取总列数 $allColumn = $currentSheet->getHighestColumn(); //获取总行数 $allRow = $currentSheet->getHighestRow(); //循环获取表中的数据，$currentRow表示当前行，从哪行开始读取数据，索引值从0开始 for ($currentRow = 1; $currentRow //从哪列开始，A表示第一列 for ($currentColumn = 'A'; $currentColumn //数据坐标 $address = $currentColumn . $currentRow; //读取到的数据，保存到数组$arr中 $data[$currentRow][$currentColumn] = $currentSheet->getCell($address)->getValue(); } } $this->save_import($data); }phpexcel导入和导出演示下载：http://www.sucaihuo.com/php/140.html
