PHP Excel导入数据到MySQL数据库

数据导出已经有了,怎么能没有数据导入呢,同样使用TP5框架,首先需要下载phpexcel.zip,放到第三方类库目录vendor目录下,然后有一个页面可以让你选择要导入的Excel文件,然后点击导入按钮调用接口:

我的模板内的数据如下图:

后端接口代码如下:

public function uplExcel(Request $request)
    {
        if (!empty($_FILES['excel']['name'])) {
            $fileName = $_FILES['excel']['name'];    //得到文件全名
            $dotArray = explode('.', $fileName);    //把文件名安.区分，拆分成数组
            $type = end($dotArray);

            if ($type != "xls" && $type != "xlsx") {
                $ret['res'] = "0";
                $ret['msg'] = "不是Excel文件，请重新上传!";
                return json_encode($ret);
            }

            //取数组最后一个元素，得到文件类型
            $uploaddir = "../uploads2/" . date("Y-m-d") . '/';//设置文件保存目录 注意包含
            if (!file_exists($uploaddir)) {
                mkdir($uploaddir, 0777, true);
            }

            $path = $uploaddir . md5(uniqid(rand())) . '.' . $type; //产生随机文件名
            //$path = "images/".$fileName; //客户端上传的文件名；
            //下面必须是tmp_name 因为是从临时文件夹中移动
            move_uploaded_file($_FILES['excel']['tmp_name'], $path); //从服务器临时文件拷贝到相应的文件夹下

            $file_path = $path;
            if (!file_exists($path)) {
                $ret['res'] = "0";
                $ret['msg'] = "上传文件丢失!" . $_FILES['excel']['error'];
                return json_encode($ret);
            }

            //文件的扩展名
            $ext = strtolower(pathinfo($path, PATHINFO_EXTENSION));
            if ($ext == 'xlsx') {
                $objReader = \PHPExcel_IOFactory::createReader('Excel2007');
                $objPHPExcel = $objReader->load($file_path, 'utf-8');
            } elseif ($ext == 'xls') {
                $objReader = \PHPExcel_IOFactory::createReader('Excel5');
                $objPHPExcel = $objReader->load($file_path, 'utf-8');
            }

            $sheet = $objPHPExcel->getSheet(0);
            $highestRow = $sheet->getHighestRow(); // 取得总行数
            $highestColumn = $sheet->getHighestColumn(); // 取得总列数
            $ar = array();
            $i = 0;
            $importRows = 0;
            for ($j = 2; $j <= $highestRow; $j++) {
                $importRows++;

                $realName = (string)$objPHPExcel->getActiveSheet()->getCell("A$j")->getValue();//需要导入的realName
                $phone = (string)$objPHPExcel->getActiveSheet()->getCell("B$j")->getValue();   //需要导入的phone
                $company = (string)$objPHPExcel->getActiveSheet()->getCell("C$j")->getValue(); //需要导入的company
                $job = (string)$objPHPExcel->getActiveSheet()->getCell("D$j")->getValue();     //需要导入的job
                $email = (string)$objPHPExcel->getActiveSheet()->getCell("E$j")->getValue();   //需要导入的email
                $ret['mdata'] = $this->addMemb($phone, $realName, $company, $job, $email);//这里就是我的数据库添加操作定义的一个方法啦,对应替换为自己的

                if ($ret['mdata'] && !is_Bool($ret['mdata'])) {
                    $ar[$i] = $ret['mdata'];
                    $i++;
                }
            }
            if ($i > 0) {
                $ret['res'] = "0";
                $ret['errNum'] = $i;
                $ret['allNum'] = $importRows;
                $ret['sucNum'] = $importRows - $i;
                $ret['mdata'] = $ar;
                $ret['msg'] = "导入完毕!";
                return json_encode($ret);
            }
            $ret['res'] = "1";
            $ret['allNum'] = $importRows;
            $ret['errNum'] = 0;
            $ret['sucNum'] = $importRows;
            $ret['mdata'] = "导入成功!";
            return json_encode($ret);
        } else {
            $ret['res'] = "0";
            $ret['msg'] = "上传文件失败!";
            return json_encode($ret);
        }
    }
