经过83次实践，发现代码的中间空了几行：就是ecshop生成代码结束 ?> 与新代码<?php 开始之间有空隙。汗，因为这个小问题折腾了最模板近一个小时。后来在网上找到相似的解决方案，现一并贴出来。

在PHP代码的最前面加入：ob_start();在excel要生成的前面加上：ob_end_clean();这样就可以解决乱码的问题了。 <?php

$sql = 'select goods_id, goods_sn, goods_name, market_price, shop_price, promote_price, is_on_sale from goods where is_delete=0 order by goods_id desc';

$data_list = $db->getAll($sql);

//以上这段代码生成Excel正常，不会出现问题，但在打开时会提示不兼容的问题。对于那些领导或者外行人士用，会感觉这个文档有问题，于是最模板找到PHPExcel来正常生成excel。

注释掉ecshop的生成代码后，PHPExcel生成的excel却变成了乱码，重新把PHPExcel单独拿出来又正常。
