php结合layui前端实现多图上传

前端html代码

<div class="layui-upload">     <button type="button" class="layui-btn layui-btn-normal" id="testList">请选择图片</button>     <span class="num_pic"></span>     <div class="layui-upload-list">         <table class="layui-table">             <thead>                 <tr>                     <th>文件名</th>                     <th id="pic">图片预览</th>                     <th>大小</th>                     <th>状态</th>                     <th id="cao">操作</th>                 </tr>             </thead>             <tbody id="demoList"></tbody>         </table>     </div>     <button type="button" class="layui-btn" id="testListAction">开始上传</button>         <span class="num_pic"></span> </div>
