一般网站后台都有人员导入或者是订单导出之类的操作,今天分享一下几种php excel cvs等文件导入导出的办法。

第一种比较简单的,自己写的,不引用任何excel类。但是会有bug,代码如下:
  首先 视图页面:
<div class="panel-body">
            <form action="./index.php" method="post" class="form-horizontal" role="form" enctype="multipart/form-data">
                <input type="hidden" name="leadExcel" value="true">  // 导入excel类型
                <input type="hidden" name="ac" value="question" />   // 将文件导入到某位置
                <label class="col-xs-12 col-sm-3 col-md-2 control-label"></label>
                <div class="help-block">请先下载导入模板,然后按照模板样式添加试题。</div>
                <div class="form-group">
                    <label class="col-xs-12 col-sm-3 col-md-2 control-label"></label>
                    <div class="col-sm-9 col-xs-12">
                          <input type="file" class="pull-left btn-default" name="inputExcel">
                    </div>
                </div>
                <div class="form-group">
                    <label class="col-xs-12 col-sm-3 col-md-2 control-label"></label>
                    <div class="col-sm-9 col-xs-12">
                         <input type="submit" class="btn pull-left btn-primary" value="导入数据">
                         <a class="btn btn-primary" href="../addons/ewei_exam/example/example_question.csv" style="margin-left: 20px;">下载导入模板</a>
                    </div>
                </div>
            </form>
        </div>

  然后是控制层页面

        if($_GPC['leadExcel'] == "true")
        {
            $filename = $_FILES['inputExcel']['name'];
            $tmp_name = $_FILES['inputExcel']['tmp_name'];

            $msg = uploadFile($filename, $tmp_name, $_GPC);

            //print_r($msg);exit;
            if ($msg == 1) {
                message('导入成功!', referer(), 'success');
            } else {
                message($msg, '', 'error');
            }
        }

  最后uploadfile这个函数中是读取excel文件内容并插入数据库,可以写在函数中,最好写到excel类中

    function uploadFile($file, $filetempname, $array)
    {
        if ($result = file_get_contents($filetempname)) {
            $result = iconv('gbk', 'utf-8', $result);
            if (empty($result)) {
                return $msg = '导入失败';
            }
            $result = preg_replace('/\n/', 'h--h', $result);
            $result = explode('h--h', $result);
            foreach ($result as $key => $ques) {
                $ques  = explode(',', $ques);
                if ($key == 0) {
                    continue;
                }
                $strs = array();
                foreach ($ques as $questi) {
                    $strs[] = preg_replace('/\s/', '', trim($questi, "\""));
                    if ($array['ac'] == 'question') {
                        upload_question($strs, time(), $array);
                    }elseif ($array['ac'] == 'member') {
                        upload_member($strs, time());
                    }
                }
            }
            $msg = '1';
        } else {
            $msg = "导入失败!";
        }
        return $msg;
    }

function upload_question($strs, $time, $array)
    {
        global $_W;

        //print_r($array);exit;

        $question_type = $strs[0];
        $level = $strs[1];
        $question = $strs[2];
        $answer = $strs[3];
        $answer1 = $strs[4];
        $answer2 = $strs[5];
        $answer3 = $strs[6];
        $answer4 = $strs[7];
        $answer5 = $strs[8];
        $answer6 = $strs[9];
        $explain = $strs[10];

        $row_num = $array['row_num'];
        
        $insert = array();
        //$insert['userid'] = $userid;
            pdo_insert('ewei_exam_question', $insert);
        }
    }

  $insert中是需要插入的数据,上面的都是获取到的数据。

  这种方式比较简单,但是导入的时候对excel文件的要求比较高,而且必须是utf8的格式。

 

第二种是引用线上封装好的的phpexcel类,这种方式基本不会出现任何问题。介绍一种:

https://github.com/dhucaichao/phpexcel.git 我放在github上了,可以自己下载。引用的代码如下:
视图层代码和上面一种一样,获取excel文件信息的代码如下
// 批量导入
function importExecl($file='', $sheet=0){
    $file = iconv("utf-8", "gb2312", $file);   //转码
    if(empty($file) OR !file_exists($file)) {
        die('file not exists!');
    }
    load()->classs('PHPExcel');
    $objRead = new PHPExcel_Reader_Excel2007();   //建立reader对象
    if(!$objRead->canRead($file)){
        $objRead = new PHPExcel_Reader_Excel5();
        if(!$objRead->canRead($file)){
            die('No Excel!');
        }
    }

    $cellName = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'AA', 'AB', 'AC', 'AD', 'AE', 'AF', 'AG', 'AH', 'AI', 'AJ', 'AK', 'AL', 'AM', 'AN', 'AO', 'AP', 'AQ', 'AR', 'AS', 'AT', 'AU', 'AV', 'AW', 'AX', 'AY', 'AZ');

    $obj = $objRead->load($file);  //建立excel对象
    $currSheet = $obj->getSheet($sheet);   //获取指定的sheet表
    $columnH = $currSheet->getHighestColumn();   //取得最大的列号
    $columnCnt = array_search($columnH, $cellName);
    $rowCnt = $currSheet->getHighestRow();   //获取总行数

    $data = array();
    for($_row=1; $_row<=$rowCnt; $_row++){  //读取内容
        for($_column=0; $_column<=$columnCnt; $_column++){
            $cellId = $cellName[$_column].$_row;
            $cellValue = $currSheet->getCell($cellId)->getValue();
//            $cellValue = $currSheet->getCell($cellId)->getCalculatedValue();
            if($cellValue instanceof PHPExcel_RichText){   //富文本转换字符串
                $cellValue = $cellValue->__toString();
            }

            $data[$_row][$cellName[$_column]] = $cellValue;
        }
    }

    return $data;
}
其中load()->classs('PHPExcel');是导入phpexcel类,我用的是框架自带的导入方式,不同框架有不同的导入方式,也可以死直接include进来。

$data是获取到的数据,可以导入数据库,例如:
function upload_staff($data)
    {
        global $_W;
        foreach ($data as $key => $value){
            if ($key == 1){
                continue;
            }
            $insert = array(
                'realname' => $value['A'],
                'mobile' => $value['B'],
                'email' => $value['C'],
                'departmentid' => find_department($value['D']),
                'position' => $value['E'],
                'birthyear' => substr(strReplace($value['F']),0,4),
                'birthmonth' => substr(strReplace($value['F']),5,2),
                'birthday' => substr(strReplace($value['F']),8,2),
                'entrytime' => strReplace($value['G']),
                'company' => find_company($_W['uid'])
            );
            $id = find_is_exists($value['B']);
            if ($id){
                $return = pdo_update('mc_members', $insert, array('uid' => $id,'uniacid'=>$_W['uniacid']));
                if (!$return){
                    return "第".($key-1)."条数据更新失败";
                }
            } else {
                $insert['uniacid'] = $_W['uniacid'];
                $id = pdo_insert('mc_members', $insert);
                if (!$id){
                    return "第".($key-1)."条数据添加失败";
                }
            }
        }
        return 1;
    }

 

   同样,也可以将数据库中的数据导出到excel中:

$list1 = array('部门','职位','手机号','姓名','发放积分','备注');
            $where = ' WHERE m.uniacid=:uniacid AND mobile <> :mobile AND d.uniacid = :duniacid';
            $param = array(':uniacid'=>$_W['uniacid'],':mobile'=>'',':duniacid'=>$_W['uniacid']);
            $lists = pdo_fetchall("SELECT d.name,m.position,m.mobile,m.realname FROM " . tablename('mc_members'). " AS m LEFT JOIN " . tablename('xfl_department'). " AS d ON m.departmentid = d.id " .$where,$param);
            $a = exportExcel($list1,$lists,'员工列表','./',true);
            header($a);

function exportExcel($title=array(), $data=array(), $fileName='', $savePath='./', $isDown=false){
    load()->classs('PHPExcel');
    $obj = new PHPExcel();

    //横向单元格标识
    $cellName = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'AA', 'AB', 'AC', 'AD', 'AE', 'AF', 'AG', 'AH', 'AI', 'AJ', 'AK', 'AL', 'AM', 'AN', 'AO', 'AP', 'AQ', 'AR', 'AS', 'AT', 'AU', 'AV', 'AW', 'AX', 'AY', 'AZ');

    $obj->getActiveSheet(0)->setTitle('sheet1');   //设置sheet名称
    $_row = 1;   //设置纵向单元格标识
    if($title){
        $_cnt = count($title);
        $obj->getActiveSheet(0)->mergeCells('A'.$_row.':'.$cellName[$_cnt-1].$_row);   //合并单元格
        $obj->setActiveSheetIndex(0)->setCellValue('A'.$_row, '数据导出:'.date('Y-m-d H:i:s'));  //设置合并后的单元格内容
        $_row++;
        $i = 0;
        foreach($title AS $v){   //设置列标题
            $obj->setActiveSheetIndex(0)->setCellValue($cellName[$i].$_row, $v);
            $i++;
        }
        $_row++;
    }

    //填写数据
    if($data){
        $i = 0;
        foreach($data AS $_v){
            $j = 0;
            foreach($_v AS $_cell){
                $obj->getActiveSheet(0)->setCellValue($cellName[$j] . ($i+$_row), $_cell);
                $j++;
            }
            $i++;
        }
    }

    //文件名处理
    if(!$fileName){
        $fileName = uniqid(time(),true);
    }

    $objWrite = PHPExcel_IOFactory::createWriter($obj, 'Excel2007');

    if($isDown){   //网页下载
        header('pragma:public');
        header("Content-Disposition:attachment;filename=$fileName.xls");
        $objWrite->save('php://output');exit;
    }

    $_fileName = iconv("utf-8", "gb2312", $fileName);   //转码
    $_savePath = $savePath.$_fileName.'.xlsx';
    $objWrite->save($_savePath);

    return $savePath.$fileName.'.xlsx';
}
exportExcel返回的是数据导入后的excel文件的地址,可以直接header过去下载。
