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 <?PHP /* $Id: index.php3,v 1.3 1999/04/14 12:12:32 borud Exp $ */ /* load the IMAP library functions we've written */ include("imapfuncs.phl"); m_login($m); ?> <HTML> <HEAD> <TITLE><?PHP echo "$M_SYSNAME"?></TITLE> </HEAD> <BODY bgcolor=#AAAAAA text=#000000 link=#440000 vlink=#440000 alink=#FF00FF> <H1 ALIGN=CENTER><?PHP echo "$M_SYSNAME"?></H1> <HR SIZE=1 NOSHADE> <P> <?PHP if ($cmd == "delete") { m_delete($marked, $m); m_list($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); } ?> <P> <HR SIZE=1 NOSHADE> <?PHP echo "User: $PHP_AUTH_USER"?> </BODY> </HTML> -------------------------------------------------------------------------------- imapfuncs.phl <?PHP /* -*-C++-*- */ /* $Id: imapfuncs.phl,v 1.4 1999/04/14 12:12:32 borud Exp $ */ /* configurable parameters */ $M_HOST = "localhost"$M_MAILSERVER = "transit.fast.no"$M_COLOR_ODD = "#CCCCCC"$M_COLOR_EVEN = "#EEEEEE"$M_COLOR_HEAD = "#AAAAFF"$M_COLOR_BG = "#FFFFFF"/* globals */ $M_PORT = 143; $M_SERVICE = "imap"$M_SYSNAME = "Simple PHP3 IMAP Interface 1.0"$M_MBOX = "{$M_HOST:$M_PORT/$M_SERVICE}"$M_REALM = "IMAP Interface"$MBOX = false; /* functions */ function m_login ($mailbox = '') { global $MBOX, $M_REALM; global $PHP_AUTH_USER, $PHP_AUTH_PW; if ($MBOX) { return true; } if (!
