PHP MIMESMTP ver 1.0 Powered by Boss_ch, Unigenius soft ware co. Ltd
All rights reserved, Copyright 2000 ;
本类用PHP通过smtp sock 操作发送MIME 类型的邮件,能够发送
HTML 格式的正文、附属类小部件,选择base64 编码
本版本是针对性个人的发送,与三人群发版本差异的是,每发送到一个人,就重新开展一遍编码,在接收端的客商看来,只是发送给他一人的。
针对三个人群发的情事,只发送一次,通过七个RCPTTO命令发送到差异的人信箱中,
说明:
请把$hostname 设为您有权力的暗中同意smtp 服务器或是在new 时钦定
把$charset 改成你的暗许字符集
Html 正文中如有图片,请用相对路线的援用"httP://host/path/image.gif";
并连上网,以保障程序能读取到图片的数码信息
设即便透过表单提交过来的Html 正文,请先用StripSlashes($html_body)把正文内容开展预管理
Html 中用到的样式表文件,请不要用<link >之类的引用,直接把体制表定义放在
<style></style>标签中

如何发送附件(转)   
自个儿反复听到这么二个标题:"我有贰个从网址发来的左券。作者如何给通过表单发送的电子邮件扩充一个附属类小部件呢?"
第一自身要说的是要产生那一个从未什么样轻巧的主意。你要很好的明白PHP或
别的的服务器端的脚本语言。当然你还要三个着实援助PHP的网址的账号。就算满意了这些前提,在你读完了本章后就足以用PHP发送带附件的电子邮件了。

  1. 附属类小部件是哪些做事的

假若你早就在PHP的手册中检索过"附属类小部件"函数,那么结果或者是何许都未有(至少在自己写本文的时间还未曾)。后来您将在花好些个年华来询问这上头的学识。

您也许会想当您给有些人发送一封带附属类小部件的电子邮件时,附属类小部件是和邮件同步放到收件人的邮箱里的(举个例子,假若你给她/她发了二个PNG的图纸文件,他/她的邮箱里会蕴藏五个txt文件(电子邮件)和三个.png文件(附属类小部件))。但那不是它的办事原理。当你进入贰个附属类小部件时,你的邮件程序把附属类小部件转变来纯文本文件,并在您写的内容(实际的电子邮件)后边插入这一个文本块。那一个,当您把持有的东西发出来后,收件人的信箱里独有多少个纯文本文件--三个并且含有附件和事实上电子邮件内容的公文。

上边是贰个带附属类小部件(二个HTML文件)电子邮件的例子。作者已经标记了内部首要的几行:

Return-Path: <[email]someone@example.com[/email]>
Date: Mon, 22 May 2000 19:17:29 0000
From: Someone <[email]someone@example.com[/email]>
To: Person <[email]person@eksempel.dk[/email]>
Message-id: <[email]83729KI93LI9214@example.com[/email]>
Content-type: multipart/mixed; boundary="396d983d6b89a"
Subject: Here's the subject

--396d983d6b89a
Content-type: text/plain; charset=iso-8859-1
Content-transfer-encoding: 8bit

This is the body of the email.

--396d983d6b89a
Content-type: text/html; name=attachment.html
Content-disposition: inline; filename=attachment.html
Content-transfer-encoding: 8bit

<html>
<head>
<title>The attachment</title>
</head>
<body>
<h2>This is the attached HTML file</h2>
</body>
</html>

--396d983d6b89a--

前边的7行是邮件的头,在那之中值得注意的是Content-type底部分。那么些头告诉邮件程序电子邮件是由三个以上的一些组成的。不含附属类小部件的邮件独有一个部分:新闻小编。带附属类小部件的电子平常最少由两有个别组成:消息和附件。那样,带七个附件的邮件由三有的构成:音信,第二个附属类小部件和第二个附属类小部件。

带附属类小部件的电子邮件的例外界分之间用分割线来分隔。分割线在Content-type头中定义。邮件的各类新部分以七个连字号(--)和分水岭起头。最后一个分割线后也会有三个连字号,表示这一个邮件中从未其余的一部分了。

在各个分水岭后有部分行,用来告诉邮件程序那个有个其他从头到尾的经过的品类。举个例子,看看上边例子中首先个分水线后边的两行--以Content-type: text/plain最早的行。那一个行表明前边的一些是ISO-8859-1字符集的纯文本。跟在第三个分水线后的行告诉邮件程序今后的有个别是三个HTML文件,它的名字是"attachment.html"。

Content-disposition那持告诉邮件程序一旦大概就以内嵌的不二等秘书籍展现附属类小部件。今后新的邮件程序会在消息后展现HTML的内容。倘诺Content-disposition被设为attachment,那么邮件程序就不会来得HTML文件的原委,而是体现一个一而再到文件的Logo(或其余的切近的事物)。收件人要看附属类小部件的剧情,必需点击那一个Logo。一般景观下,假使附属类小部件是有的文本(包蕴HTML),Content-disposition会被设为inline,那是因为前日天津大学学多邮件程序能够不依赖别的浏览器而直白展现附属类小部件(文本)的源委。借使附件不是文件(比如图片或别的类似的剧情),Content-disposition就设为attachment。

  1. 用PHP生成带附属类小部件的电子邮件

这里一个事例,告诉您只要把叁个定义好的HTML文件加为邮件的附件:

<?php
# 大家先是写实际的新闻内容
$emailBody = "This is text that goes into the body of the email.";

# 然后大家要作为附属类小部件的HTML文件
$attachment = "<html>
<head>
<title>The attached file</title>
</head>
<body>
<h2>This is the attached HTML file</h2>
</body>
</html>";

# 创设在邮件中分隔不相同部分的分割线。
# 基本上,分水岭能够是随意的字符串。
# 可是重视的一些是规定四个写邮件的人
# 那会轻巧写出的字符串,所以我们用
# uniqid函数来发出一个随便的字符串。
$boundary = uniqid( "");

# 今后大家要确立邮件头。不要忘了插入
# Content-type头来注解这一个邮件包蕴八个或越来越多的附属类小部件。
$headers = "From: [email]someone@example.com[/email]
Content-type: multipart/mixed; boundary="$boundary"";

# 好,现在我们已经有了邮件的有所内容。
# 下一件事是修改邮件的重心。
$emailBody = "--$boundary
Content-type: text/plain; charset=iso-8859-1
Content-transfer-encoding: 8bit

$emailBody

--$boundary
Content-type: text/html; name=attachment.html
Content-disposition: inline; filename=attachment.html
Content-transfer-encoding: 8bit

$attachment

--$boundary--";

# 以往能够把邮件发出去了
mail( "[email]person@eksempel.dk[/email]", "The subject", $emailBody, $headers);
?>

  1. 把客商上传的公文作为附属类小部件

您大概会以为下边包车型客车例证难以领悟,但下边...。在上边包车型地铁事例辽宁中华南理经济大学程公司作更难了,因为我们要用贰个表单让客商上传他们的文本,并把那几个文件作为我们要发的邮件的附属类小部件。麻烦的是大家不可能事先了然文书的MIME类型。在前头的例证中,大家曾经知晓该它是多个HTML文件,所以给这些附属类小部件设置Content-type头是很简单的。在底下的例子中,MIME类型或许是即兴的,因为客商大概会上传多个HTML文件,壹个PNG文件,多个vCard文件,只怕别的的事物。让大家来探视例子:

<?php
# 今后我们来扭转表单。在发生可以上传文件的表单时,
# 不要忘了把<form>标签的"enctype"属性设为"multipart/form-data".
echo "<form action='$PHP_SELF' enctype='multipart/form-data' method='post'>n";
echo "<input type='text' name='from'><br>n";
echo "<input type='text' name='to'><br>n";
echo "<input type='text' name='subject'><br>n";
echo "<input type='file' name='attachment'><br>n";
echo "<textarea name='body'></textarea><br>n";
echo "<input type='submit' name='send' value='Send'>n";
echo "</form>n";

# 若是客商已经按了"Send"按键"
if ($send) {
# 定义分割线
$boundary = uniqid( "");

# 生成邮件头
$headers = "From: $from
Content-type: multipart/mixed; boundary="$boundary"";

# 鲜明上传文件的MIME类型
if ($attachment_type) $mimeType = $attachment_type;
# 若是浏览器未有一些名文件的MIME类型,
# 我们能够把它设为"application/unknown".
else $mimeType = "application/unknown";

# 鲜明文件的名字
$fileName = $attachment_name;

# 打开文件
$fp = fopen($attachment, "r");
# 把一切文件读入二个变量
$read = fread($fp, filesize($attachment));

# 好,今后变量$read中保留的是带有全部文件内容的文本块。
# 未来我们要把那一个文本块转变来邮件程序能够读懂的格式
# 大家用base64方法把它编码
$read = base64_encode($read);

# 以往大家有三个用base64方法编码的长字符串。
# 下一件事是要把这一个长字符串切成由每行77个字符组成的小块
$read = chunk_split($read);

# 今后大家能够创设邮件的基本点
$body = "--$boundary
Content-type: text/plain; charset=iso-8859-1
Content-transfer-encoding: 8bit

$body

--$boundary
Content-type: $mimeType; name=$fileName
Content-disposition: attachment; filename=$fileName
Content-transfer-encoding: base64

$read

--$boundary--";

# 发送邮件
mail($to, $subject, $body, $headers);
}
?>

那正是全体内容。假令你不能够很好地领略地方的事例,作者的建议是给您本人发送多少个带附属类小部件的邮件,然后稳重切磋邮件的源代码。
