PHP通过mail函数发送带附件的邮件

来源：互联网发布：唱衰中国知乎编辑：程序博客网时间：2024/05/06 03:20

首先下载Magic WinMail Server，安装一个自己的邮件服务器，

访问http://127.0.0.1:6080，注册个帐户后，就可以对邮件进行收发管理拉。

接下来，php就可以利用mail函数通过你的邮件服务器发送邮件，运行 mail.php就行啦。

注：代码中标注红色代表需要准备的图片或文档。

代码如下：

mail.php:

error_reporting(63);

include('html_mime_mail.inc');

/***************************************

** Example of usage.

***************************************/

/***************************************

** Read the file background.gif into

** $backgrnd.

***************************************/

$filename = 'background.gif';

$backgrnd = fread($fp = fopen($filename, 'r'), filesize($filename));

fclose($fp);

/***************************************

** Read the file into $attachment.

** 举例：这里我们同时发送一张图片和一个txt文本.

***************************************/

$filename1 = 'picture.jpg';

$filename2 = 'test.txt';

$attachment1 = fread($fp1 = fopen($filename1, 'r'), filesize($filename1));

$attachment2 = fread($fp2 = fopen($filename2, 'r'), filesize($filename2));

fclose($fp1);

fclose($fp2);

/***************************************

** Create the mail object. Optional headers

** argument. Do not put From: here, this

** will be added when $mail->send

***************************************/

$mail = new html_mime_mail("X-Mailer: Html Mime Mail Class/r/n");

/***************************************

** If sending an html email, then these

** two variables specify the text and

** html versions of the mail. Don't

** have to be named as these are. Just

** make sure the names tie in to the

** $mail->add_html() command further down.

***************************************/

$text = 'This is a test.';

$html = '<HTML><BODY BACKGROUND="background.gif"><FONT FACE="Verdana, Arial" COLOR="#FF0000"> Success!</FONT><P></BODY></HTML>';

/***************************************

** Add the text, html and embedded images.

** Each embedded image has to be added

** using $mail->add_html_image() BEFORE

** calling $mail->add_html(). The name

** of the image should match exactly

** (case-sensitive) to the name in the html.

***************************************/

$mail->add_html_image($backgrnd, 'background.gif', 'image/gif');

$mail->add_html($html, $text);

/***************************************

** If not sending an html email, then

** this is used to set the plain text

** body of the email.

***************************************/

// $mail->body = 'fsss';

/***************************************

** This is used to add an attachment to

** the email. $filename1 & 2 是要发送的附件名称.

***************************************/

$mail->add_attachment($attachment1, $filename1, 'application/octet-stream');

$mail->add_attachment($attachment2, $filename2, 'application/octet-stream');

/***************************************

** Builds the message.

***************************************/

$mail->build_message();

/***************************************

** Sends the message. $mail->build_message()

** is seperate to $mail->send so that the

** same email can be sent many times to

** differing recipients simply by putting

** $mail->send() in a loop.

**蓝色标注是欲邮件接收方的用户和地址,紫色标注是邮件发送方的用户和地址。

**picture是指接收邮件用户所看到的邮件主题。

$mail->send('Lucas.liu','xuepingliu@hotmail.com', 'From Name', 'lucas@solid.com', 'picture','');
