How can one integrate a method for setting email priority in Swift_Message when using SwiftMailer in PHP?

To set email priority in Swift_Message when using SwiftMailer in PHP, you can use the setPriority() method provided by Swift_Message. You can specify the priority level as an integer value ranging from 1 (highest) to 5 (lowest). This allows you to prioritize important emails over others in the recipient's inbox.

// Create a new Swift_Message instance
$message = new Swift_Message();

// Set email content, subject, recipients, etc.

// Set email priority
$message->setPriority(1); // 1 being the highest priority

// Send the email using SwiftMailer
$mailer->send($message);
