send() method is not called

if method is used for trying an action like sending mail if you use like that it will try to send that mail and give back process result like "yup I did send this mail" or "nope I can't send it" and you make you write less code to achieve same result and trust me when you building a real life project those little saving become really important things :)

It would be easier to tell if you post your code but from what you've written I think I may know your problem.

You would not call:

PHPMailer->send()

You would first have to instantiate the PHPMailer object then call it like so:

$mail = new PHPMailer;

$mail.send()

Here is the github page

Yup that's another way of doing it and the most common with PHPMailer.

Heres and example:

<?php
$mail = new PHPMailer;

$mail->From = "from@yourdomain.com";
$mail->FromName = "Full Name";

$mail->addAddress("recipient1@example.com", "Recipient Name");
$mail->isHTML(true);

$mail->Subject = "Subject Text";
$mail->Body = "<i>Mail body in HTML</i>";
$mail->AltBody = "This is the plain text version of the email content";

if(!$mail->send()) 
{
    echo "Mailer Error: " . $mail->ErrorInfo;
} 
else 
{
    echo "Message has been sent successfully";
}
?>
