如何使用PHP发送包含附件的电子邮件
通常需要把 附件 比如 aa.txt 做处理
然后 通过 fsockopen 打开 对方 邮件地址
通过 fwrite 把 附件内容 写进对方的地址 邮件内容中
例如 下面这种 需要这么处理
最下方 最长的那一段 实际上就是 附件的真实内容 也就是说 aa.txt里边的内容 是以这种方式传送的 当然了这是编码过以后的 结果
那么在对方收到你的 邮件后 在读取时 也是需要解码 然后给你 看的
最终 解码后 你看到的 结果 就是 aa.txt 下载打开后 里边就会有内容了
Content-Type: text/x-c++;

php如何发送邮件

PHP POP3如何获取邮件附件内容
可以考虑使用正则表达式，例子代码：
?php
$s='------=_NextPart_001_0013_01CFED3C.C561B7D0-- ------=_NextPart_000_0012_01CFED3C.C561B7D0 Content-Type: application/octet-stream; name="aa.txt" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="aa.txt"';
if (preg_match('|filename="([^"]+)"|',$s,$r)) echo '文件名：'.$r[1];
?
请问附件是什么？ 还有在邮件上的具体信息
附件一般是伴随邮件出现，个人理解就是邮件里表达不了或者需要对方确认的一些文件。附件: 发邮件时附加一个文件, 与邮件内容一起传送至收件人.
一般附件不宜过大, 否则要麽传送时间长, 要麽被拒收; 附件中最好是压缩包, 而不是将播放文件(mp3,wma,rm)、可执行文件(exe,bat)等直接附加上去, 很容易被拒收或当垃圾邮件拦截.
发送步骤如下：1打开你的邮箱2.写新邮件3.打开新邮件的窗口，有一排功能按钮，其中有一个是添加附件4.点击此按钮，之后会出现一个对话框，浏览，找到你要发的附件，选择确定5.待附件上传成功，点击发送即可。
同样，如果需要预览或者下载邮件，点击邮件里的附件信息即可。
不同的邮箱对于附件的容量要求不一样，你可以在网上寻找!
