PHP Mail Send source code

Long time to write something ..... Recently, life is depressing .... For the life and tired, tidy up the example of e-mail sent, there are many online, I am also a good extract, test OK, home Mail class smtp_email_class.php as follows:
<?php
Class Email
{
function Send_mail ($to, $subject, $message, $from, $from _name, $mailformat =1)
{
if (Function_exists (' Mail '))
{

$headers = ' from: '. $from _name. ' < '. $from. ' > '. ' \ r \ n ";
$headers. = ' to: '. $to. " \ r \ n ";
if ($mailformat)
{$headers. = "content-type:text/html;\r\n";}
Else
{$headers. = "content-type:text/plain;\r\n";}
$headers. = "charset=gb2312\r\n\r\n";

$message = Str_replace ("\ R", "', $message);

[Email protected] ($to, Str_replace ("\ n", "", $subject), $message, $headers);

if (! $mail _return)
{
return $to. ' Send unsuccessful ';
}

return 1;
}
}

function Send_win32_mail ($to, $subject, $message, $from, $from _name, $host, $port, $mailformat =1)
{
Ini_set (' SMTP ', $host);
Ini_set (' Smtp_port ', $port);
Ini_set (' Sendmail_from ', $from);

$headers = ' from: '. $from _name. ' < '. $from. ' > '. ' \ r \ n ";
$headers. = ' to: '. $to. " \ r \ n ";
if ($mailformat)
{$headers. = "content-type:text/html;\r\n";}
Else
{$headers. = "content-type:text/plain;\r\n";}
$headers. = "charset=gb2312\r\n\r\n";

foreach (Explode (', ', $to) as $touser)
{
$touser = Trim ($touser);
if ($touser)
{
[Email protected] ($touser, $subject, $message, $headers);
if (! $mail _return)
{
return $touser. ' Send unsuccessful ';
}
}
}
return 1;
}

Send E_Mail via sock, no attachments supported,
//-------------------------------------------------------------------------------------------------------

/*
1. Create the sock and open the connection
2. Set to blocking mode
3. Test whether the SMTP answer code is 220,220 for mail Service readiness
4. Send user authentication, set by user
1=ehlo Host Domain \ r \ n
0=helo Host Domain \ r \ n
?. Read the server-side send back data to the client
The data sent by smtp.163.com is:
250-pipelining//pipelining command, which tells the client to send multiple commands at once to increase speed, here PHP
is not used because the PHP single file runs or is single-threaded
250-auth LOGIN PLAIN
250-auth=login PLAIN
8bitmime//get this line that is the SMTP server sends the end, waiting for the client to send commands
5. Send Auth Login command
6. Send User Name
7. Send Password
?. After the authentication has been successful,
8. Add from to the server
9. Add to the server
10. Send the data command and start typing the email to "." Number over
11. Write the contents of the message
12. Sending message content to an SMTP server
13. Send the QUIT command to end the session
