send email php smtp
I migrated an application to a platform without a local transport agent (MTA). I did not want to configure an MTA, so I wrote this xxmail function to replace mail() with calls to a remote SMTP server. Hopefully it is of some use.
function xxmail($to, $subject, $body, $headers)
{
$smtp = stream_socket_client('tcp://smtp.yourmail.com:25', $eno, $estr, 30);
$B = 8192;
$c = "\r\n";
$s = '[email protected]';
fwrite($smtp, 'helo ' . $_ENV['HOSTNAME'] . $c);
$junk = fgets($smtp, $B);
// Envelope
fwrite($smtp, 'mail from: ' . $s . $c);
$junk = fgets($smtp, $B);
fwrite($smtp, 'rcpt to: ' . $to . $c);
$junk = fgets($smtp, $B);
fwrite($smtp, 'data' . $c);
$junk = fgets($smtp, $B);
// Header
fwrite($smtp, 'To: ' . $to . $c);
if(strlen($subject)) fwrite($smtp, 'Subject: ' . $subject . $c);
if(strlen($headers)) fwrite($smtp, $headers); // Must be \r\n (delimited)
fwrite($smtp, $headers . $c);
// Body
if(strlen($body)) fwrite($smtp, $body . $c);
fwrite($smtp, $c . '.' . $c);
$junk = fgets($smtp, $B);
// Close
fwrite($smtp, 'quit' . $c);
$junk = fgets($smtp, $B);
fclose($smtp);
}
