Question

i am trying to send something like news letter Via Zend_Mail but after 12 mail i got this message
Fatal error: Maximum execution time of 30 seconds exceeded in C:\Program Files\Zend\Apache2\htdocs\forga\library\Zend\Mail\Protocol\Abstract.php on line 321
my Code is like:

'port' => '587',
'username' =>'xxxxx#xxxxx.com',
'password' => 'xxxxxxxx'
);
$transport = new Zend_Mail_Transport_Smtp($smtpHost, $smtpConf);
foreach($users as $user)
{
$mail = new Zend_Mail();
$mail->setFrom("noreply#forga.com", 'Forga');
$mail->setSubject($subject);
if($html=='on')
$mail->setBodyHtml($message);
else
$mail->setBodyText($message);
$mail->addto($user);
$transport->send($mail);
}

Answer 1

From the script timeout you get I'd assume your host is slow to send eMails and simply cannot handle bulk sending of eMails. You could increase the time until a script times out with
set_time_limit — Limits the maximum execution time
A more elegant way would be to send the eMails in separate processes asynchronously. Check out
Mysteries of Asynchronous Processing by Padraic Brady Part 1, 2 and 3.
Part 3 deals with eMails specifically.

Answer 2

Check out my answer on another posting on parallel processing in PHP Multithreading/Parallel Processing in PHP. I think it's relevant. If you need something to be done outside of the individual request it should probably be passed to some kind of queue.

Answer 3

Do you manage the web server yourself?
Up to version 5.3.0, set_time_limit() only works in safe mode. (deprecated in recent PHP).
You can set safe mode in php.ini.
See also max_execution_time in php.ini.

Answer 4

By the looks of your code your sending a single email to each on individually from your server.. Try doing the following.
$smtpHost = 'smtp.gmail.com';
$smtpConf = array(
'auth' => 'login',
'ssl' => 'tls',
'port' => '587',
'username' =>'xxxxx#xxxxx.com',
'password' => 'xxxxxxxx'
);
$transport = new Zend_Mail_Transport_Smtp($smtpHost, $smtpConf);
$mail = new Zend_Mail();
$mail->setFrom("noreply#forga.com", 'Forga');
$mail->setSubject($subject);
$html=='on' ?$mail->setBodyHtml($message) : $mail->setBodyText($message);
foreach($users as $user)
{
$mail->addto($user);
}
$transport->send($mail);
No i might actually be wrong with this because the other email addresses may be visible to all recipients, im not sure if that's only the concerning section of the email.
