我有点担心,如果这个功能将能够正确地对多数电子邮件和网络邮件客户端的方式应该得到承认的邮件,特别是我最关心这个疑惑:这是用PHP发送电子邮件的正确方法吗?
- 是UTF -8声明和附件是否形成良好?
- 我需要使用quoted_printable_decode()吗?如果是,在哪里?
- 内容传输编码:7或8位?我一直看到7,但因为我发送一个UTF-8编码的邮件,我不确定。
- 我应该使用mb_send_mail()还是mail()就够了?
编辑:我不知道为什么,但代码显示不正确,我将其提供@http://gist.github.com/104818
编辑2:我知道其他替代品(库)的电子邮件处理,但为了我自己的好奇心和知识,我只想知道这段代码是否100%好,或者它是否有问题。

血腥的好回答琼斯先生。我希望你得到赏金+1 – da5id 2009-05-08 00:19:47
我同意,Zend_Mail拥有你需要的一切和更多!使用由许多人开发的库,它通常具有较少的错误。 – Kekoa 2009-05-11 15:43:58
