PHP send mail on windows causing it to 'hang' after sending email - php

Question

we're starting to build a web app. My colleague is developing on linux, and I am running via a WAMP stack running windows xp. We're using Zend.
When we submit a form and send an email using Zend email, the email would send and then I would get a blank screen, wheras on the linux machine the app would continue normally.
So I wrote my own little script, mail.php which uses phpmailer - and the exact same thing happens, the email sends, and then blank screen. So we have:
if(!$mail->Send())
{
echo "Mailer Error: " . $mail->ErrorInfo;
}
else
{
echo "Message has been sent";
}
So there is no error reported, the email sends, but "Message has been sent" never prints to the screen (or anything else, normal HTML too).
I am not very technical, so apologies if there are obvious debug steps to take. Is there something peculiar to windows php config that I have missed?
It's an off-site SMTP server with authentication.

Answer 1

Sounds like you are getting an error, but just not seeing it. Make sure you have this somewhere in your code
ini_set( 'display_errors', 1 );
error_reporting( E_ALL );
And inspect your apache logs for 500 errors as well.

Answer 2

PHP has it's own error log, when in doubt check there. You should be able to locate it by running
<?php
phpinfo();
?>
It should be located in the PHP Core section - if it's blank, edit your php.ini file and turn log_errors on and specify where you want the file to be.
Errors I couldn't get to display I've found using this.
UPDATE
Did some digging and it seems that Zend_Mail is essentially a wrapper for PHP's mail() function according to the documentation: http://framework.zend.com/manual/en/zend.mail.html
With that in mind there's some information on PHP's mail() function in the PHP manual that you're going to want to look at regarding SendMail http://www.php.net/manual/en/ref.mail.php the first comment on the page (as of this writing) has all the details on configuring your WAMP server to behave like a *nix server - at least as far as mail() operations go ;-)

I use phpmailer with success on a windows box (my dev machine). Can I see the setup code? I do something like the below. One thing is you need to make sure openssl module is installed in php if you are using ssl. Take a look at the below. Make sure your SMTPDebug flag is set to have some output that you can work with.
<?php
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->Host = "blah.com";
$mail->SMTPDebug = 1;
$mail->SMTPAuth = true;
$mail->SMTPSecure = "ssl";
$mail->Host = "mail.blah.com";
$mail->Port = 465;
$mail->Username = "noreply#blah.com";
$mail->Password = "smtppass";
$mail->SetFrom('noreply#blah.com', 'Blah Name');
$mail->AddReplyTo("noreply#blah.com", "Blah Name");
$mail->Sender = "noreply#blah.com"
?>

apologies for taking so long to answer this. The problem was caused by a firewall in the office blocking outbound SMTP traffic. I am still not sure as to why it returned nothing - but outside of this office when it was tested the php errors for invalid smtp etc. returned fine. Just a case of getting the appropriate ports allowed on the network.
Thanks everyone for their help.
