    IMAP、POP3、 NNTP(邮件传输协议)

    安装

    要使这些函数生效,你必须在编译 PHP 的时候添加 --with-imap[=DIR] 选项, DIR 表示c-client安装前缀。比如上面提到的例子中,你可以使用 --with-imap=/usr/local/imap-2000b. 根据以上描述,这个路径是指向你先前创建的文件夹。对于 Windows 用户,应该在php.ini文件中引入php_imap.dll.

    Windows 2000之前的系统是不支持的 IMAP 的。这是因为通过SSL连接邮件服务器时使用了加密功能。

    Note: 因为取决于 c-client 是如何配置的,所以你应该向 PHP 配置行添加--with-imap-ssl=/path/to/openssl/ 或者 --with-kerberos=/path/to/kerberos 配置信息。

    Warning

    IMAP,recode,YAZ 和 Cyrus 扩展不能同时使用,因为它们共享了相同 的内部符号。注意:Yaz2.0 及以上版本不存在此问题。

    运行时配置

    这些函数的行为受php.ini中的设置影响。

    For all the people coming here praying for:
    1) a dead-easy way to read MIME attachments, or
    2) a dead-easy way to access POP3 folders
    Look no further.

    [EDIT BY danbrown AT php DOT net: Contains a bugfix by "mn26826" on 09-JUN-2010, which fixed the erroneous reference to $imap as the parameter passed to imap_mailboxmsginfo() within the user function pop3_stat(). This was intended to be $connection.]
    [EDIT BY visualmind AT php DOT net: Contains a bugfix by "elias-jobview" on 17-AUG-2010, which fixed the error in pop3_list function which didn't have: return $result]
    [EDIT BY danbrown AT php DOT net: Contains a bugfix by "chrismeistre" on 09-SEP-2010, which fixed the erroneous reference to $mbox (should be $connection) in the pop3_list() function.]
