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);
}
}
