关于php发送mail的问题，急切想知道，请大家多多关注！

[Liubin]

我用php中的mail()函数发送mail,为什么只能以文本方式而不能以html格式发送？
如何在我的mail中发送图片或超级连接？
除了mail()还有其他方法吗？

[alan_turing]

除了用MAIL（）还可以采用调用邮件服务器上的sendmail的命令来实现！

[dsds]

可以的：
在PHP中有个函数叫：HTMLSpecialChars，用来把一些特殊的字符转换成HTML的格式
举个例子：
$Text=preg_replace("/\[url\](.+?)\[\/url\]/is","<a href=\\1>\\1</a>",$Text);
这是一个支持连接的语句，当然你可以定义很多这样的HTML，不过有点麻烦。:)

你只要把正文内容格式处理成MIME的邮件格式就行了。那样的话，你就可以发送有附件而且任何类型的邮件方式。
