download .xls file in php(cpanel) using href

Question

I had .xls file in report folder

<a href="http://website.com/report/salesList.xls" download>
    <input type="button" class="btn btn-success" value="Download Report">  
</a> 

was not working.

Instead:

<a href="http://website.com/images/123.png" download>
    <input type="button" class="btn btn-success" value="Download Image">
</a> 

was working.

Need to give any permission for .xls format files?

Thanks.

通过自动生成excel文件的php文件中的chmod($file,0644)更改.xls文件的权限。
