Thinkphp+phpexcel导出和导入【原创】

首先我们看下导出的HTML

<a href="{:U('Index/excelExport')}">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 < $head_num - 1; $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 action="{:U('Index/upload')}" method="post" enctype="multipart/form-data">
    <div class="control-group">
        <label>Excel表格：</label>
        <input type="file"  name="file"/>
    </div>
    <div class="control-group">
        <input type="submit"  value="导入" />
    </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 <= $allRow; $currentRow++) {
        //从哪列开始，A表示第一列
        for ($currentColumn = 'A'; $currentColumn <= $allColumn; $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);
}
