Sending mail with Gmail’s SMTP server with fsockopen
Today i was trying to find a way to send mail from my localhost (xampp) with Gmails SMTP server. I found some code in popular and also fastest forum engine – punBB.
I got the codes and did some cleanup for working fine as an external script. Here is the codes -
<?php
//this functin processes the server return codes and generates errors if needed
function server_parse($socket, $expected_response)
{
$server_response = '';
while (substr($server_response, 3, 1) != ' ')
{
if (!($server_response = fgets($socket, 256)))
echo 'Couldn\'t get mail server response codes. Please contact the forum administrator.', __FILE__, __LINE__;
}
if (!(substr($server_response, 0, 3) == $expected_response))
echo 'Unable to send e-mail. Please contact the forum administrator with the following error message reported by the SMTP server: "'.$server_response.'"', __FILE__, __LINE__;
}
//
// This function was originally a part of the phpBB Group forum software phpBB2 (http://www.phpbb.com).
// They deserve all the credit for writing it. I made small modifications for it to suit PunBB and it's coding standards.
// -------> This message is from punBB developer
//
function smtp_mail($to, $subject, $message, $headers = '')
{
$recipients = explode(',', $to);
$user = '<your mail id>';
$pass = '<your password>';
$smtp_host = 'ssl://smtp.gmail.com';
$smtp_port = 465;
if (!($socket = fsockopen($smtp_host, $smtp_port, $errno, $errstr, 15)))
echo "Could not connect to smtp host '$smtp_host' ($errno) ($errstr)", __FILE__, __LINE__;
server_parse($socket, '220');
fwrite($socket, 'EHLO '.$smtp_host."\r\n");
server_parse($socket, '250');
fwrite($socket, 'AUTH LOGIN'."\r\n");
server_parse($socket, '334');
fwrite($socket, base64_encode($user)."\r\n");
server_parse($socket, '334');
fwrite($socket, base64_encode($pass)."\r\n");
server_parse($socket, '235');
fwrite($socket, 'MAIL FROM: <tareq1988@gmail.com>'."\r\n");
server_parse($socket, '250');
foreach ($recipients as $email)
{
fwrite($socket, 'RCPT TO: <'.$email.'>'."\r\n");
server_parse($socket, '250');
}
fwrite($socket, 'DATA'."\r\n");
server_parse($socket, '354');
fwrite($socket, 'Subject: '.$subject."\r\n".'To: <'.implode('>, <', $recipients).'>'."\r\n".$headers."\r\n\r\n".$message."\r\n");
fwrite($socket, '.'."\r\n");
server_parse($socket, '250');
fwrite($socket, 'QUIT'."\r\n");
fclose($socket);
return true;
}
// Send the mail
if(smtp_mail('tareq1988@gmail.com', 'Hi! Test Mail', 'This is a test mail from xampp with fsockopen()'))
{
echo "Mail sent";
}
else
{
echo "Some error occured";
}
?>
