直接上代码:

html:

<tr>
   <td><table width="100%" border="0" cellspacing="0" cellpadding="0">
            <tr>
                <td width="10%" height="30" align="right" bgcolor="#f2f2f2" class="left_txt2">上传文件</td>
                <td width="1%" bgcolor="#f2f2f2">&nbsp;</td>
                <td width="32%" height="30" bgcolor="#f2f2f2">
                    <input type="file" name="excelPacket" class="file">
                </td>
            </tr>
            <tr>
                <td height="30" colspan="4" align="center" class="left_txt"><input type="submit" name="button" id="button" value="创建" />
                    &nbsp;
                    <input type="reset" name="button2" id="button2" value="重置" /></td>
            </tr>
        </table</td>

php:(另外在该文件包上一级建立一个文件夹用于存放要导入的excel表)

记得引入PHPexcel类包
