php-swiftmailerHow to use SMTP with Swiftmailer?

Swiftmailer is a popular library for sending emails using PHP. It supports sending emails using SMTP protocol. To use SMTP with Swiftmailer, you need to create a Swift_SmtpTransport instance and pass it to Swift_Mailer instance.

// Create the Transport
$transport = (new Swift_SmtpTransport('smtp.example.org', 25))
  ->setUsername('your username')
  ->setPassword('your password')
;

// Create the Mailer using your created Transport
$mailer = new Swift_Mailer($transport);

The code above creates a Swift_SmtpTransport instance with host smtp.example.org and port 25, and sets the username and password for authentication. Then it creates a Swift_Mailer instance with the created transport.

Parts of the code:

• Swift_SmtpTransport: Class for sending emails using SMTP protocol.
• smtp.example.org: Hostname of the SMTP server.
• 25: Port of the SMTP server.
• setUsername(): Method to set the username for authentication.
• setPassword(): Method to set the password for authentication.
• Swift_Mailer: Class for sending emails.
