拿来即用的thinkphp5 + phpspreadsheet 导入excel功能

view层

<form action="{:url('system/exceladd1/daoru')}" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" /> 
<br />
<input type="submit" name="submit" value="Submit" />
</form>

controller层

<?php
