tp5 Excel导入

要处理的表格

1.建表

2.将PHPExcel类文件复制到框架中extend目录下

3.视图层

<form action="{:url('index/excel_add')}" method="post" enctype="multipart/form-data">
    <h2>Excel导入</h2>
    <table>
        <tr>
            <td>
                <input type="file" name="excel">
            </td>
            <td>
                <input type="submit">
            </td>
        </tr>
    </table>
</form>
4.控制器层

<?php
namespace app\index\controller;
use think\Controller;
use think\Loader;
use think\Request;
class Index extends Controller
{
    public function index()
    {
        return view();
    }
    public function excel_add(){
        //限制大小
        ini_set('memory_limit','1024M');
        //引入类文件
        Loader::import('PHPExcel.Classes.PHPExcel');
        //实例化上传类
        $excelobj = new \PHPExcel();
        //接收文件
        $file = $_FILES['excel'];
        //获取后缀名并改为小写
        $extension = strtolower(pathinfo($file['name'],PATHINFO_EXTENSION));
        //判断Excel版本
        if ($extension=='xlsx'){
            $readobj = \PHPExcel_IOFactory::createReader('excel2007');
        }else{
            $readobj = \PHPExcel_IOFactory::createReader('excel5');
        }
        //读取数据并处理
        $res = $readobj->load($file['tmp_name']);
        $arr = $res->getSheet(0)->toArray();
        unset($arr[0]);  //删除第一行表头
        foreach ($arr as $k =>$val){
            $list[$k]['name']=$val[0];
            $list[$k]['sex']=$val[1];
            $list[$k]['age']=$val[2];
            $list[$k]['class']=$val[3];
            $list[$k]['type']=$val[4];

        }
        //执行添加
        if (Db('student')->insertAll($list)){
            $this->success('导入成功');
        }
    }
}
