我想使用邮件接收类的朋友可能比较少,但是发送邮件的类使用的朋友比较多啊,下面我来分别给大家介绍php邮件接收与发送类实现程序详解,希望对大家所有帮助哦。

主要的改进如下：

1、新增了listMessages方法,用于列表邮件列表,且带有分页功能,更加方便调用:

 'date', 'direction' => 'desc')
 *
 */
function listMessages($page = 1, $per_page = 25, $sort = null) {
}
?>

2、新增了两个编码转换的方法,主要用于对邮件的相关信息进行编码转换,调用方法如下:

connect();
$maillist = $obj->listMessages();
print_r($maillist);
?>
运行结果大致如下： 
Array 
( 
	[res] => Array 
		( 
		 [0] => stdClass Object 
		  ( 
		   [subject] => 解决PHP邮件接收类的乱码问题 
		   [from] => xxx  
		   [to] => abc  
		   [date] => Mon, 28 Jan 2013 14:23:06 +0800 (CST) 
		   [message_id] => <2afc51061915f95-00004.Richmail.00037000523146269922@xxx.com> 
					[size] => 42259 
					[uid] => 1 
					[msgno] => 1 
					[recent] => 1 
					[flagged] => 0 
					[answered] => 0 
					[deleted] => 0 
					[seen] => 0 
					[draft] => 0 
					[body] => 邮件内容 
		  ) 
		) 
 [start] => 1 
	[limit] => 25 
	[sorting] => Array 
		( 
			[by] =>  
			[direction] =>  
		) 
	[total] => 47 
	[pages] => 2 
)

receivemail.class.php类文件,代码如下:

下面是一个php邮件发送的类的一个函数,代码如下:

get_address($this->strip_comment($from));
    $body = ereg_replace("(^|(rn))(.)", "1.3", $body);
    $header = "MIME-Version:1.0rn";
    if ($mailtype == "HTML") {
        $header.= "Content-Type:text/htmlrn";
    }
    $header.= "To: " . $to . "rn";
    if ($cc != "") {
        $header.= "Cc: " . $cc . "rn";
    }
    $header.= "From: 报名邮件.<" . $from . ">rn";
    $header.= "Subject: " . $subject . "rn";
    $header.= $additional_headers;
    $header.= "Date: " . date("r") . "rn";
    $header.= "X-Mailer:By Redhat (PHP/" . phpversion() . ")rn";
    $utfheader = iconv("UTF-8", "GB2312", $header);
    list($msec, $sec) = explode(" ", microtime());
    $header.= "Message-ID: <" . date("YmdHis", $sec) . "." . ($msec * 1000000) . "." . $mail_from . ">rn";
    $TO = explode(",", $this->strip_comment($to));
    if ($cc != "") {
        $TO = array_merge($TO, explode(",", $this->strip_comment($cc)));
    }
    if ($bcc != "") {
        $TO = array_merge($TO, explode(",", $this->strip_comment($bcc)));
    }
    $sent = TRUE;
    foreach ($TO as $rcpt_to) {
        $rcpt_to = $this->get_address($rcpt_to);
        if (!$this->smtp_sockopen($rcpt_to)) {
            $this->log_write("Error: Cannot send email to " . $rcpt_to . "n");
            $sent = FALSE;
            continue;
        }
        if ($this->smtp_send($this->host_name, $mail_from, $rcpt_to, $utfheader, $body)) {
            $this->log_write("E-mail has been sent to <" . $rcpt_to . ">n");
        } else {
            $this->log_write("Error: Cannot send email to <" . $rcpt_to . ">n");
            $sent = FALSE;
        }
        fclose($this->sock);
        $this->log_write("Disconnected from remote hostn");
    }
    return $sent;
}
?>

我们如何调用这个类呢？示例代码如下:

在这里需要一个smtp服务器,我们可以注册一个126的邮箱, 在上面的代码中,修改成你自己注册的邮箱地址和用户名、密码即可。
