public class MIMEBase64 {
/*
Base64 uses a 65 character subset of US-ASCII,
allowing 6 bits for each character so the character
"m" with a Base64 value of 38, when represented
in binary form, is 100110.
With a text string, let's say "men" is encoded this
is what happens :
The text string is converted into its US-ASCII value.
The character "m" has the decimal value of 109
The character "e" has the decimal value of 101
The character "n" has the decimal value of 110
When converted to binary the string looks like this :
m 01101101
e 01100101
n 01101110
These three "8-bits" are concatenated to make a
24 bit stream
011011010110010101101110
This 24 bit stream is then split up into 4 6-bit
sections
011011 010110 010101 101110
We now have 4 values. These binary values are
converted to decimal form
27 22 21 46
And the corresponding Base64 character are :
b W V u
The encoding is always on a three characters basis
(to have a set of 4 Base64 characters). To encode one
or two then, we use the special character "=" to pad
until 4 base64 characters is reached.
ex. encode "me"
01101101 01100101
0110110101100101
011011 010110 0101
111111 (AND to fill the missing bits)
011011 010110 010100
b W U
b W U = ("=" is the padding character)
so "bWU=" is the base64 equivalent.
encode "m"
01101101
011011 01
111111 (AND to fill the missing bits)
011011 010000
b Q = = (two paddings are added)
Finally, MIME specifies that lines are 76 characters wide maximum.

а почему такая длинная прога?
вот на Паскале, но не факт что правильно

base64_encode
да фиг знает, мне на джавах надо было к письму аттачмент прихреначить это первое что гугль выдал
вот такая мне и нужна, токмо как её запрогать на php?
Она уже есть. Учись пользоваться мануалом.

base64_encode
(PHP 3, PHP 4 )
base64_encode -- Encodes data with MIME base64
Description
string base64_encode ( string data)
base64_encode returns data encoded with base64. This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies.
Base64-encoded data takes about 33% more space than the original data.
как я понял, она не правильно работает на сервере. сейчас убедюсь в своей неправоте.
дело в том что данный код:
function XMail( $from, $to, $subj, $text, $filename)
{
$f = fopen($filename,"rb");
$un = strtoupper(uniqid(time;
$head = "From: $from\n";
$head .= "To: $to\n";
$head .= "Subject: $subj\n";
$head .= "X-Mailer: PHPMail Tool\n";
$head .= "Reply-To: $from\n";
$head .= "Mime-Version: 1.0\n";
$head .= "Content-Type:multipart/mixed;";
$head .= "boundary=\"----------".$un."\"\n\n";
$zag = "------------".$un."\nContent-Type:text/html;\n";
$zag .= "Content-Transfer-Encoding: 8bit\n\n$text\n\n";
$zag .= "------------".$un."\n";
$zag .= "Content-Type: application/octet-stream;";
$zag .= "name=\"".basename($filename)."\"\n";
$zag .= "Content-Transfer-Encoding:base64\n";
$zag .= "Content-Disposition:attachment;";
$zag .= "filename=\"".basename($filename)."\"\n\n";
$zag .= chunk_split(base64_encode(fread($f,filesize($filename."\n";
if (!@mail("$to", "$subj", $zag, $head
return 0;
else
return 1;
}
работает у меня,
но не работает на сервере (аттач искажается).

проверяй заголовки. ошибка может быть в них.
