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