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([&#39;form&#39;,&#39;upload&#39;],function(){
        var form=layui.form;
        var upload=layui.upload;
        upload.render({ //允许上传的文件后缀
            elem: &#39;#myfile&#39;
            ,url: "{:url(&#39;Logisticscompany/inserline&#39;)}"
            ,accept: &#39;file&#39; //普通文件
            ,exts: &#39;xls|excel|xlsx&#39; //只允许上传压缩文件
            ,done: function(res){
                if(res.code==1){
                    layer.msg(&#39;上传成功,已解析数据&#39;,{icon:6});
                    location.href="{:url(&#39;Logisticscompany/lists&#39;)}";
                }else{
                    layer.msg(&#39;解析失败&#39;,{icon:5});
                }
            }
        });
        form.on(&#39;submit(formsub)&#39;,function(data){
            layer.msg(&#39;导入数据具体详情未协商确认,待确认后处理&#39;);
            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();
            //获取表单上传文件
            $file = request()->file(&#39;file&#39;);
            $info = $file->validate([&#39;ext&#39; => &#39;xlsx,xls&#39;])->move(ROOT_PATH . &#39;public&#39;);  //上传验证后缀名,以及上传之后移动的地址  E:\wamp\www\bick\public
            if($info)
            {
                $exclePath = $info->getSaveName();  //获取文件名
                $file_name = ROOT_PATH . &#39;public&#39; . DS . $exclePath;//上传文件的地址
                $file_types = explode ( ".", $_FILES [&#39;file&#39;] [&#39;name&#39;] );

                }
                else if($file_type==&#39;xlsx&#39;){
                    $objReader =\PHPExcel_IOFactory::createReader("Excel2007");
                }
                $obj_PHPExcel =$objReader->load($file_name, $encode = &#39;utf-8&#39;);  //加载文件内容,编码utf-8
                $excel_array=$obj_PHPExcel->getSheet(0)->toArray();   //转换为数组格式

                        &#39;msg&#39;=>&#39;已获取信息&#39;,
                    ];
