Multiple Emails with PHPMailer - php

Question

I am trying to send emails to mutiple people with different bodies using one code, using PHPMailer via SMTP. My code is as follows :
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
require_once("class.phpmailer.php");
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPAuth = true;
$mail->Host = "xxxxxxxx";
$mail->SetFrom('xx#xxx.com');
$mail->Subject = "System Change";
$add = array("a", "b", "c");
foreach ( $add as $address ) {
$current = clone $mail;
if ( $address == 'a' )
{
$current->AddAddress('xx#xx.com');
$current->MsgHTML("Message1");
$current->send();
}
if ( $address == 'b' )
{
$current->AddAddress('xx#xx.com');
$current->MsgHTML("Message2");
$current->send();
}
if ( $address == 'c' )
{
$current->AddAddress('xx#xx.com');
$current->MsgHTML("Message3");
$current->send();
}
}
exit;
if($mail->Send())
{ echo "SUCCESSFUL"; }
else echo "ERROR IN SENDING MAILS";
exit;
}
?>
The issue is it is sending mails but only sending the first 2, and then displaying a timeout error. Is there any setting that I need to change or is it a problem with my code? Have edited it in many ways but it ends up sending only 2 mails instead of 3. Appreciate any help :) Thanks!

Answer 1

This will likely solve your issue, there is no need to clone the PHPMailer object.
I have sent hundreds of emails at once using this method with no timeout issues.
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
set_time_limit(120);
require_once("class.phpmailer.php");
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPAuth = true;
$mail->Host = "xxxxxxxx";
$mail->SetFrom('xx#xxx.com');
$mail->IsHTML(true);
$mail->Subject = "System Change";
$add = array("a", "b", "c");
foreach ( $add as $address ) {
$mail->clearAttachments();
$mail->clearAllRecipients();
if ( $address == 'a' )
{
$mail->AddAddress('xx#xx.com');
$mail->Body("Message1");
$mail->send();
}
if ( $address == 'b' )
{
$mail->AddAddress('xx#xx.com');
$mail->Body("Message2");
$mail->send();
}
if ( $address == 'c' )
{
$mail->AddAddress('xx#xx.com');
$mail->Body("Message3");
$mail->send();
}
}
if($mail->send()) echo "SUCCESSFUL";
else echo "ERROR IN SENDING MAILS";
exit;
}

Answer 2

Add the following line of code after the opening of the foreach loop
set_time_limit(60);
With this line of code, you give every mail 60 seconds to be sent. This number can be as high as you want. But I should try to keep it as low as possible
You are resetting the timelimit to 60 seconds every time this piece of code is run. Resetting it back to zero.

Answer 3

Base your code on the mailing list example provided with PHPMailer. Generally you don't ever want to be doing this kind of thing on a page load via a web server - run it from cron where timeouts are not an issue.
