1.打印内容发现中文昵称带了表情特殊字符，导致phpexcel导出时无法识别，会出现部分字段数据丢失的问题
[13] => Array
(
[payment_success_at] =>
[user_name] => 💋.琳琳💃
[remarks] =>
[product_name] => 香菇
[sku_name] => 斤
[product_property] => 斤
[price_original] => 5.50
[price_current] => 5.50
[consignee] => 💋.琳琳💃
)
2.解决需要做字符集转码
conv('gb2312//ignore', 'utf-8', iconv('utf-8', 'gb2312//ignore', $value));
打印内容： [13] => Array ( [user_name] => .琳琳 [remarks] => [product_name] => 香菇 [sku_name] => 斤 [product_property] => 斤 [price_original] => 5.50 [price_current] => 5.50 [product_quantity] => 2 [consignee] => .琳琳 )
转码后就可以正常导出了
