1、先在github里面下载PHPexcel这个类库
2、解压之后把它复制到extend里面
控制器代码如下:
1 <?php
2 /**
3 * Created by PhpStorm.
4 * User: luxiao
5 * Date: 2017/5/8
6 * Time: 16:49
7 */
8 namespace appindexcontroller;
9
10 use thinkLoader;
11 use thinkController;
12
13 class Excel extends Controller
14 {
15 function excel()
16 {
17 $path = dirname(__FILE__); //找到当前脚本所在路径
18 Loader::import('PHPExcel.Classes.PHPExcel'); //手动引入PHPExcel.php
19 Loader::import('PHPExcel.Classes.PHPExcel.IOFactory.PHPExcel_IOFactory'); //引入IOFactory.php 文件里面的PHPExcel_IOFactory这个类
20 $PHPExcel = new PHPExcel(); //实例化
21
22 $PHPSheet = $PHPExcel->getActiveSheet();
23 $PHPSheet->setTitle("demo"); //给当前活动sheet设置名称
24 $PHPSheet->setCellValue("A1","姓名")->setCellValue("B1","分数");//表格数据
25 $PHPSheet->setCellValue("A2","张三")->setCellValue("B2","2121");//表格数据
26 $PHPWriter = PHPExcel_IOFactory::createWriter($PHPExcel,"Excel2007"); //创建生成的格式
27 header('Content-Disposition: attachment;filename="表单数据.xlsx"'); //下载下来的表格名
28 header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
29 $PHPWriter->save("php://output"); //表示在$path路径下面生成demo.xlsx文件
30 }
31 }
调用excel方法就可以生成一个表格了,后续的根据自己的需要自己去写代码.
PHPexcel 表格数据导入数据库 city 表,在这之前自己先创建好表单,我这次用的都是地址数据表做的测试:
1 function inserExcel()
2 {
3 Loader::import('PHPExcel.Classes.PHPExcel');
4 Loader::import('PHPExcel.Classes.PHPExcel.IOFactory.PHPExcel_IOFactory');
5 Loader::import('PHPExcel.Classes.PHPExcel.Reader.Excel5');
6 //获取表单上传文件
7 $file = request()->file('excel');
8 $info = $file->validate(['ext' => 'xlsx'])->move(ROOT_PATH . 'public' . DS . 'uploads'); //上传验证后缀名,以及上传之后移动的地址
9 if ($info) {
10 // echo $info->getFilename();
11 $exclePath = $info->getSaveName(); //获取文件名
12 $file_name = ROOT_PATH . 'public' . DS . 'uploads' . DS . $exclePath; //上传文件的地址
13 $objReader =PHPExcel_IOFactory::createReader('Excel2007');
14 $obj_PHPExcel =$objReader->load($file_name, $encode = 'utf-8'); //加载文件内容,编码utf-8
15 echo "<pre>";
16 $excel_array=$obj_PHPExcel->getsheet(0)->toArray(); //转换为数组格式
17 array_shift($excel_array); //删除第一个数组(标题);
18 $city = [];
19 foreach($excel_array as $k=>$v) {
20 $city[$k]['Id'] = $v[0];
21 $city[$k]['code'] = $v[1];
22 $city[$k]['path'] = $v[2];
23 $city[$k]['pcode'] = $v[3];
24 $city[$k]['name'] = $v[4];
25 }
26 Db::name('city')->insertAll($city); //批量插入数据
27 } else {
28 echo $file->getError();
29 }
