Integrate Mailazy with PHP

PHPMailer

PHPMailer is available on Packagist (using semantic versioning), and installation via Composer is the recommended way to install PHPMailer. Just add this line to your composer.json file:

"phpmailer/phpmailer": "^6.2"

Or run

composer require phpmailer/phpmailer

Note that the vendor folder and the vendor/autoload.php script are generated by Composer; they are not part of PHPMailer.

If you want to use the Gmail XOAUTH2 authentication class, you will also need to add a dependency on the league/oauth2-client package in your composer.json.

Alternatively, if you're not using Composer, you can download PHPMailer as a zip file, (note that docs and examples are not included in the zip file), then copy the contents of the PHPMailer folder into one of the include_path directories specified in your PHP configuration and load each class file manually:

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
require 'path/to/PHPMailer/src/Exception.php';
require 'path/to/PHPMailer/src/PHPMailer.php';
require 'path/to/PHPMailer/src/SMTP.php';

If you're not using the SMTP class explicitly (you're probably not), you don't need a use line for the SMTP class. Even if you're not using exceptions, you do still need to load the Exception class as it is used internally.

A Example:
SMTPDebug = SMTP::DEBUG_SERVER; //Enable verbose debug output
$mail->isSMTP(); //Send using SMTP
$mail->Host = 'smtp.mailazy.com'; //Set the SMTP server to send through
$mail->SMTPAuth = true; //Enable SMTP authentication
$mail->Username = 'mailazy_apikey'; //SMTP username
$mail->Password = 'mailazy_secret'; //SMTP password
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; //Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` encouraged
$mail->Port = 587;
//TCP port to connect to, use 465 for PHPMailer::ENCRYPTION_SMTPS above


//Recipients
$mail->setFrom('from@example.com', 'Mailer');
$mail->addAddress('joe@example.net', 'Joe User'); //Add a recipient
$mail->addAddress('ellen@example.com'); //Name is optional
$mail->addReplyTo('info@example.com', 'Information');
$mail->addCC('cc@example.com');
$mail->addBCC('bcc@example.com');

//Content
$mail->isHTML(true); //Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body in bold!';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
$mail->send();
echo 'Message has been sent';
} catch (Exception $e) {
echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
