PHP email topic PHP SMTP class
/**********************************
PHP MIMESMTP ver 1.0 Powered by Boss_ch, Unigenius soft ware co. Ltd
All rights reserved, Copyright 2000;
This class uses PHP to send MIME type emails through smtp sock operation, and can send
HTML format The text and attachments are encoded in base64
This version is for individual sending. Different from the multi-person version, every time it is sent to a person, it is re-encoded. From the perspective of the user at the receiving end, it is just sent to him. A person's.
For multi-person crowd sending, it is only sent once and sent to different people's mailboxes through multiple RCPTTO commands.
Instructions:
Please set $hostname as the default smtp server that you have permissions or Specify
when new and change $charset to your default character set
If there are pictures in the HTML text, please use absolute path references "httP://host/path/image.gif";
And connect to the Internet to ensure that the program can read the data information of the image
If the Html text is submitted through a form, please use StripSlashes ($html_body) to preprocess the text content first
Used in Html For style sheet files, please do not use references such as . Place the style sheet definition directly in the
tag.

如何發(fā)送附件（轉(zhuǎn)）? ?
我經(jīng)常聽(tīng)到這樣一個(gè)問(wèn)題："我有一個(gè)從網(wǎng)站發(fā)來(lái)的合同。我如何給通過(guò)表單發(fā)送的電子郵件增加一個(gè)附件呢？"
首先我要說(shuō)的是要做到這個(gè)沒(méi)有什么簡(jiǎn)單的辦法。你要很好的理解PHP或
其它的服務(wù)器端的腳本語(yǔ)言。當(dāng)然你還要一個(gè)真正支持PHP的網(wǎng)站的賬號(hào)。如果滿(mǎn)足了這個(gè)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(jīng)在PHP的手冊(cè)中搜索過(guò)"附件"函數(shù)，那么結(jié)果可能是什么都沒(méi)有（至少在我寫(xiě)本文的時(shí)間還沒(méi)有）。后來(lái)你就要花很多時(shí)間來(lái)了解這方面的知識(shí)。

你也許會(huì)想當(dāng)你給某個(gè)人發(fā)送一封帶附件的電子郵件時(shí)，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(gè)PNG的圖片文件，他/她的信箱里會(huì)包含一個(gè)txt文件（電子郵件）和一個(gè).png文件（附件））。但這不是它的工作原理。當(dāng)你加入一個(gè)附件時(shí)，你的郵件程序把附件轉(zhuǎn)換成純文本文件，并在你寫(xiě)的內(nèi)容（實(shí)際的電子郵件）后面插入這個(gè)文本塊。這個(gè)，當(dāng)你把所有的東西發(fā)出來(lái)后，收件人的信箱里只有一個(gè)純文本文件--一個(gè)同時(shí)包含附件和實(shí)際電子郵件內(nèi)容的文件。

Below is an example of an email with an attachment (an HTML file). I have marked some important lines:

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

This is the attached HTML file

--396d983d6b89a--



The first 7 lines are The header of the email, of which it is worth noting the Content-type header part. This header tells the mail program that the email consists of more than one part. An email without attachments has only one part: the message itself. Emails with attachments usually consist of at least two parts: the message and the attachment. In this way, a message with two attachments consists of three parts: the message, the first attachment, and the second attachment.

Emails with attachments are separated by dividing lines between different parts. The dividing line is defined in the Content-type header. Each new section of the message begins with two hyphens (--) and a delimiter. There are also two hyphens after the last dividing line, indicating that there are no other parts of the email.

After each delimiter there are lines that tell the mail program the type of content in this section. For example, take a look at the two lines after the first dividing line in the example above - the lines starting with Content-type: text/plain. What follows these lines is plain text for the ISO-8859-1 character set. The line following the second delimiter tells the mail program that the current section is an HTML file and its name is "attachment.html".

Content-disposition tells the email program to display attachments inline if possible. The new email program now displays HTML content after the message. If Content-disposition is set to attachment, the mail program will not display the contents of the HTML file, but will display an icon (or something similar) connected to the file. To see the content of the attachment, the recipient must click this icon. Under normal circumstances, if the attachment is some text (including HTML), Content-disposition will be set to inline. This is because most email programs can directly display the content of the attachment (text) without using other browsers. If the attachment is not text (such as a picture or other similar content), Content-disposition is set to attachment.

2. Use PHP to generate emails with attachments

Here is an example of how to add a defined HTML file as an attachment to an email:

< ?php
# We first write the actual message content
$emailBody = "This is text that goes into the body of the email.";

# Then we want to attach the HTML file
$attachment = "




< ;h2>This is the attached HTML file

";

# Creates a dividing line that separates different parts of the email.
# Basically, the dividing line can be any string.
# But the important point is to identify the person who wrote the email.
# This will write a random string, so we use the
# uniqid function to generate a random string.
$boundary = uniqid( "");

# Now we need to create the email header. Don’t forget to insert the
# Content-type header to indicate that this email contains one or more attachments.
$headers = "From: [email]someone@example.com[/email]
Content-type: multipart/mixed; boundary="$boundary"";

# OK, now We already have all the contents of the email.
# The next thing to do is modify the body of the email.
$emailBody = "--$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--";

# Now you can send the email
mail( "[email]person@eksempel.dk[/email ]", "The subject", $emailBody, $headers);
?>



3. Attach files uploaded by users as attachments

You might You may find the above example difficult to understand, but below...In the example below things are even harder because we are using a form to let users upload their file and attaching the file to the email we are sending. The trouble is that we don't know the MIME type of the file in advance. In the previous example, we already knew that it was an HTML file, so setting the Content-type header for this attachment was simple. In the example below, the MIME type could be arbitrary, since the user might upload an HTML file, a PNG file, a vCard file, or something else. Let's look at an example:

# Now let's generate the form. When generating a form that can upload files,
# Don’t forget to set the "enctype" attribute of the

tag to "multipart/form-data".
echo "n";
echo "
n";
echo "
n";
echo "
n" ;
echo "
n";
echo "< br>n";
echo "n";
echo "

n";

# If the user has pressed the "Send" button"
if ($send) {
# Define the boundary
$boundary = uniqid( "");

# Generate email Header
$headers = "From: $from
Content-type: multipart/mixed; boundary="$boundary"";

# Determine the MIME type of the uploaded file
if ($ attachment_type) $mimeType = $attachment_type;
# If the browser does not specify the MIME type of the file,
# we can set it to "application/unknown".
else $mimeType = "application/unknown" ;

# Determine the name of the file
$fileName = $attachment_name;

# Open the file
$fp = fopen($attachment, "r");
# Read the entire file into a variable
$read = fread($fp, filesize($attachment));

# Okay, now the variable $read saves the text block containing the entire file content.
# Now we need to convert this text block into a format that the mail program can read
# We use the base64 method to encode it
$read = base64_encode($read);

# Now we have a long string encoded using base64 method.
# The next thing is to chop this long string into smaller chunks consisting of 76 characters per line
$read = chunk_split($read);

# Now we can build The body of the email
$body = "--$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--";

# Send email
mail($to, $subject, $body, $headers);
}
?>


That’s all. If you don't understand the above example well, my suggestion is to send yourself a few emails with attachments and then carefully study the source code of the emails.
