What are some best practices for managing email templates with dynamic content in PHP applications?

When managing email templates with dynamic content in PHP applications, it's best practice to separate the email content from the code logic to make it easier to maintain and update. One way to achieve this is by using a template engine like Twig or Blade to handle dynamic content in email templates.

// Example using Twig template engine
require_once 'vendor/autoload.php';

$loader = new \Twig\Loader\FilesystemLoader('path/to/templates');
$twig = new \Twig\Environment($loader);

$template = $twig->load('email_template.twig');
$emailContent = $template->render([
    'name' => 'John Doe',
    'message' => 'Hello, this is a dynamic email content.'
]);

// Send email using $emailContent
