如何验证电子邮件地址？ [英] How to validate email-addresses?
问题描述
大家好，
我有一个拥有几家鞋店的客户。
如果客户希望在销售时收到通知，可以留下他们的电子邮件地址。
输入用instr验证（）
我正在检查@和。 （必填）并检查空格（不允许）。
但是：很多（5-10％）的地址仍然是错的; （提供商不存在）或电子邮件地址无效（不再）。
发送群发邮件时，一个令人讨厌的问题是从合并中获取虚假地址。
其他人如何处理此问题？
我想我可以使用某种提供者 - 表格？
" jo ***** @ hotmail.com"没关系
" jo ***** @ hotnail.com"是错的
谢谢，
Arno R
Hi all,
I have a client with several shoe-shops.
Customers can leave their email-address if they want to be notified when there is a sale.
Input is validated with instr()
I am checking for @ and . (required) and also checking for spaces (not allowed).
But: A LOT (5-10%) of the addresses still are wrong; (provider doesn''t exist) or email-address not valid (anymore).
When sending bulk-mail its a nasty problem to get the false addresses out of the ''mergetable''.
How are others dealing with this?
I guess I could use some kind of a ''provider''-table?
"jo*****@hotmail.com" is OK
"jo*****@hotnail.com" is wrong
Thanks,
Arno R

对不起可能造成的混淆......
我说''提供者''我的意思是域名当然。
主要问题是@

Sorry for possible confusion ...
Where I say ''provider'' I mean ''domain'' of course.
The main problem is the string after the @

我认为这个问题的答案在本讨论的主题之外的一些代码中，你可能会尝试一些PHP代码：

I think the answer for this problem lies in some code which is outside the
topic of this discussion, but you might try some PHP code:
