php-symfonyHow to use the PHP Symfony mailer?

The PHP Symfony mailer is a library that allows you to send emails from your Symfony application. It is easy to use and provides a lot of flexibility.

Example code

use Symfony\Component\Mailer\Mailer;
use Symfony\Component\Mailer\Transport\Smtp\EsmtpTransport;

$transport = new EsmtpTransport('smtp.example.com', 25);
$mailer = new Mailer($transport);

$email = (new TemplatedEmail())
    ->from('[email protected]')
    ->to('[email protected]')
    ->subject('Hello!')
    ->htmlTemplate('emails/hello.html.twig')
    ->context(['name' => 'John Doe']);

$mailer->send($email);

This example code will send an email from [email protected] to [email protected] with the subject Hello! and the HTML template emails/hello.html.twig with the context variable name set to John Doe.
