PHP郵件專題 PHP SMTP類? ?

/***********************************
PHP MIMESMTP ver 1.0 Powered by Boss_ch， Unigenius soft ware co. Ltd
All rights reserved, Copyright 2000 ;
本類用PHP通過smtp sock 操作發(fā)送MIME 類型的郵件，可以發(fā)送
HTML 格式的正文、附件，采用base64 編碼
本版本是針對個人的發(fā)送，與多人群發(fā)版本不同的是，每發(fā)送到一個人，就重新進行一次編碼，在接收端的用戶看來，只是發(fā)送給他一個人的。
針對多人群發(fā)的情況，只發(fā)送一次，通過多個RCPTTO命令發(fā)送到不同的人信箱中，
說明：
請把$hostname 設為你有權限的默認smtp 服務器或是在new 時指定
把$charset 改成你的默認字符集
Html 正文中如有圖片，請用絕對路徑的引用"httP://host/path/image.gif";
并連上網，以保證程序能讀取到圖片的數據信息
如果是通過表單提交過來的Html 正文，請先用StripSlashes($html_body)把正文內容進行預處理
Html 中用到的樣式表文件，請不要用之類的引用，直接把樣式表定義放在
標簽中

如何發(fā)送附件（轉）? ?
我經常聽到這樣一個問題："我有一個從網站發(fā)來的合同。我如何給通過表單發(fā)送的電子郵件增加一個附件呢？"
首先我要說的是要做到這個沒有什么簡單的辦法。你要很好的理解PHP或
其它的服務器端的腳本語言。當然你還要一個真正支持PHP的網站的賬號。如果滿足了這個前提，在你讀完了本章后就可以用PHP發(fā)送帶附件的電子郵件了。

1. 附件是如何工作的

如果你曾經在PHP的手冊中搜索過"附件"函數，那么結果可能是什么都沒有（至少在我寫本文的時間還沒有）。后來你就要花很多時間來了解這方面的知識。

你也許會想當你給某個人發(fā)送一封帶附件的電子郵件時，附件是和郵件一起放到收件人的信箱里的（比如，如果你給他/她發(fā)了一個PNG的圖片文件，他/她的信箱里會包含一個txt文件（電子郵件）和一個.png文件（附件））。但這不是它的工作原理。當你加入一個附件時，你的郵件程序把附件轉換成純文本文件，并在你寫的內容（實際的電子郵件）后面插入這個文本塊。這個，當你把所有的東西發(fā)出來后，收件人的信箱里只有一個純文本文件--一個同時包含附件和實際電子郵件內容的文件。

下面是一個帶附件（一個HTML文件）電子郵件的例子。我已經標注了其中重要的幾行：

Return-Path:
Date: Mon, 22 May 2000 19:17:29 +0000
From: Someone
To: Person
Message-id:
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

This is the attached HTML file

--396d983d6b89a--



前面的7行是郵件的頭，其中值得注意的是Content-type頭部分。這個頭告訴郵件程序電子郵件是由一個以上的部分組成的。不含附件的郵件只有一個部分：消息本身。帶附件的電子通常至少由兩部分組成：消息和附件。這樣，帶兩個附件的郵件由三部分組成：消息，第一個附件和第二個附件。

帶附件的電子郵件的不同部分之間用分界線來分隔。分界線在Content-type頭中定義。郵件的每個新部分以兩個連字號（--）和分界線開始。最后一個分界線后也有兩個連字號，表示這個郵件中沒有其它的部分了。

在每個分界線后有一些行，用來告訴郵件程序這個部分的內容的類型。比如，看看上面例子中第一個分界線后面的兩行--以Content-type: text/plain開頭的行。這些行說明后面的部分是ISO-8859-1字符集的純文本。跟在第二個分界線后的行告訴郵件程序現在的部分是一個HTML文件，它的名字是"attachment.html"。

Content-disposition這持告訴郵件程序如果可能就以內嵌的方式顯示附件?，F在新的郵件程序會在消息后顯示HTML的內容。如果Content-disposition被設為attachment，那么郵件程序就不會顯示HTML文件的內容，而是顯示一個連接到文件的圖標（或其它的類似的東西）。收件人要看附件的內容，必須點擊這個圖標。一般情況下，如果附件是一些文本（包含HTML），Content-disposition會被設為inline，這是因為現在大部分郵件程序能夠不借助其它瀏覽器而直接顯示附件（文本）的內容。如果附件不是文本（比如圖片或其它類似的內容），Content-disposition就設為attachment。

2. 用PHP生成帶附件的電子郵件

這里一個例子，告訴你如果把一個定義好的HTML文件加為郵件的附件：

# 我們首先寫實際的消息內容
$emailBody = "This is text that goes into the body of the email.";

# 然后我們要作為附件的HTML文件
$attachment = "

This is the attached HTML file

";

# 建立在郵件中分隔不同部分的分界線。
# 基本上，分界線可以是任意的字符串。
# 但是重要的一點是確定一個寫郵件的人
# 這會隨意寫出的字符串，所以我們用
# uniqid函數來產生一個隨機的字符串。
$boundary = uniqid( "");

# 現在我們要建立郵件頭。不要忘了插入
# Content-type頭來說明這個郵件包含一個或更多的附件。
$headers = "From: [email]someone@example.com[/email]
Content-type: multipart/mixed; boundary=\"$boundary\"";

# 好，現在我們已經有了郵件的所有內容。
# 下一件事是修改郵件的主體。
$emailBody = "--$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--";

# 現在可以把郵件發(fā)出去了
mail( "[email]person@eksempel.dk[/email]", "The subject", $emailBody, $headers);
?>



3. 把用戶上傳的文件作為附件

你也許會覺得上面的例子難以理解，但下面...。在下面的例子中事情更難了，因為我們要用一個表單讓用戶上傳他們的文件，并把這個文件作為我們要發(fā)的郵件的附件。麻煩的是我們不能預先知道文件的MIME類型。在前面的例子中，我們已經知道該它是一個HTML文件，所以給這個附件設置Content-type頭是很簡單的。在下面的例子中，MIME類型可能是任意的，因為用戶可能會上傳一個HTML文件，一個PNG文件，一個vCard文件，或者其它的東西。讓我們來看看例子：

# 現在我們來生成表單。在產生可以上傳文件的表單時，
# 不要忘了把

標簽的"enctype"屬性設為"multipart/form-data".
echo "

\n";
echo "
\n";
echo "
\n";
echo "
\n";
echo "
\n";
echo "
\n";
echo "\n";
echo "

\n";

# 如果用戶已經按了"Send"按鈕"
if ($send) {
# 定義分界線
$boundary = uniqid( "");

# 生成郵件頭
$headers = "From: $from
Content-type: multipart/mixed; boundary=\"$boundary\"";

# 確定上傳文件的MIME類型
if ($attachment_type) $mimeType = $attachment_type;
# 如果瀏覽器沒有指定文件的MIME類型，
# 我們可以把它設為"application/unknown".
else $mimeType = "application/unknown";

# 確定文件的名字
$fileName = $attachment_name;

# 打開文件
$fp = fopen($attachment, "r");
# 把整個文件讀入一個變量
$read = fread($fp, filesize($attachment));

# 好，現在變量$read中保存的是包含整個文件內容的文本塊。
# 現在我們要把這個文本塊轉換成郵件程序可以讀懂的格式
# 我們用base64方法把它編碼
$read = base64_encode($read);

# 現在我們有一個用base64方法編碼的長字符串。
# 下一件事是要把這個長字符串切成由每行76個字符組成的小塊
$read = chunk_split($read);

# 現在我們可以建立郵件的主體
$body = "--$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--";

# 發(fā)送郵件
mail($to, $subject, $body, $headers);
}
?>


這就是全部內容。如果你不能很好地理解上面的例子，我的建議是給你自己發(fā)送幾個帶附件的郵件，然后仔細研究郵件的源代碼。
