tp5 （layui ）excel导入

1.composer安装PHPExcel

下载安装composer

其次 cmd切换到项目根目录 运行命令：composer require phpoffice/phpexcel

注意：

        1.运行可能会报错OpenSSL之类的 去php.ini中开启extension=php_openssl.dll扩展，去掉分号

        2.还有可能出现 找不到匹配的包的错误，这是因为我本地用的phpstudy的nts版本，这个版本比较特殊同时支持apache和nginx，只是本地虚拟环境开发测试用的PHP版本，所以匹配不到，应该切换正常版本在运行命令安装

2.前端代码

           <div class="layui-form-item" >
                <label class="layui-form-label">导入专线</label>
                <div class="layui-input-inline">
                    <div class="layui-upload">
                        <button type="button" name="myfile" class="layui-btn" id="myfile"><i class="layui-icon">�</i>上传文件</button>
                    </div>
                </div>
            </div>

<script type="text/javascript">
    layui.use(['form','upload'],function(){

        var form=layui.form;
        var upload=layui.upload;

        upload.render({ //允许上传的文件后缀
            elem: '#myfile'
            ,url: "{:url('Logisticscompany/inserline')}"
            ,accept: 'file' //普通文件
            ,exts: 'xls|excel|xlsx' //只允许上传压缩文件
            ,done: function(res){
                if(res.code==1){
                    layer.msg('上传成功,已解析数据',{icon:6});
                    location.href="{:url('Logisticscompany/lists')}";
                }else{
                    layer.msg('解析失败',{icon:5});
                }
            }
        });

        form.on('submit(formsub)',function(data){
            layer.msg('导入数据具体详情未协商确认,待确认后处理');
            return false;
        })


    })

</script>

3.controller

    /**
     * excel导入网点
     */
    public function  insert(){
        if(request() -> isPost())
        {
            vendor("PHPExcel.PHPExcel"); //方法一
            $objPHPExcel =new PHPExcel();

            $file = request()->file('file');
            $info = $file->validate(['ext' => 'xlsx,xls'])->move(ROOT_PATH . 'public');  //上传验证后缀名,以及上传之后移动的地址  E:wampwwwickpublic

                $obj_PHPExcel =$objReader->load($file_name, $encode = 'utf-8');  //加载文件内容,编码utf-8
                $excel_array=$obj_PHPExcel->getSheet(0)->toArray();   //转换为数组格式
                array_shift($excel_array);  //删除第一个数组(标题);
