WebMail

sadly

这是一段Web Mail的示范代码，功能不是很强，但是结构还比较完整，主要的功能如查看文件夹，查看信件，回复，写信都有。但是程序中没有考虑附件解读和发送的问题。 (原文在 这里)。仅推荐给希望了解Webmail编程的网友做个参考。更加完善的Webmail请大家到 这里查找。

请注意：程序中使用了http认证功能，此功能需配合apache服务器使用。

--------------------------------------------------------------------------------

将以下代码分别存为 index.php3, imapfuncs.phl

配置imapfuncs.phl文件中的$M_HOST = "localhost"; $M_MAILSERVER = "transit.fast.no";

然后浏览 index.php3 即可.

--------------------------------------------------------------------------------

index.php3

/* load the IMAP library functions we've written */

include("imapfuncs.phl");

m_login($m);

?>

elseif ($cmd == "display") {

m_display($n, $m);

}

elseif ($cmd == "compose" || $cmd == "reply") {

m_compose($n, $m);

}

elseif ($cmd == "send") {

m_send($to, $subject, $body);

m_list($m);

}

else {

m_list($m);

}

?>
