Send mail with SMTP. No error message but not working

[nerd99]

I am attempting to send an email from my website via SMTP.

 

Knowing that my site's host supports PEAR I have used PEAR’s Mail function. Here is my code...

 

<?php
require_once "Mail.php";

$from = "Me <me@email>";
$to = "You <you@email>";
$subject = "Subject";
$body = "Insert Message Here";

$host = "hostdetails";
$username = "username";
$password = "password";

$headers = array ('From' => $from,
   'To' => $to,
   'Subject' => $subject);
$smtp = Mail::factory('smtp',
   array ('host' => $host,
     'auth' => true,
     'username' => $username,
     'password' => $password));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
   echo("<p>" . $mail->getMessage() . "</p>");
  } else {
   echo("<p>Message successfully sent!</p>");
  }
?>

 

This gave me an error saying:

'Class 'Net_SMTP' not found in /usr/local/php52/pear/Mail/smtp.php on line 210'

 

So, using siteground as my host, I followed this tutorial - www.siteground.com/tutorials/php-mysql/pear_modules.htm and thanks to a very helpful blog entry (http://goonanism.com/blog/2010/06/08/using-pear-to-send-email-via-smtp/) I discovered that I needed to install the following packages in the following directories:

 

pear

    /Mail

        /RFC822.php

        /mail.php

        /mock.php

        /null.php

        /sendmail.php

        /smtp.php

        /smtpmx.php

    /Net

        /SMTP.php

        /Socket.php

    /Mail.php

    /PEAR.php

    /PEAR5.php

 

Back to the siteground tutorial, I created the php.ini file as directed. This is where I think I've gone wrong as I don't really know what I'm doing! I created a blank document and inserted the following code as directed:

include_path = ".:/usr/lib/php:/usr/local/lib/php:/home/my_cPanel_username/pear";

 

This file is saved in the following place:

/public_html/php.ini

 

Is this what they intended?

 

Now, I am getting nothing. No error message, no message saying the email has been sent. The page loads fine but nothing has happened.

 

Does anyone have any suggestions on what I could try or what the problem may be?
