What template engines or tools can PHP developers use to streamline SEO optimization for subpages?

When optimizing subpages for SEO in PHP, developers can utilize template engines like Twig or Blade to streamline the process. These template engines allow for the separation of logic and presentation, making it easier to insert dynamic content and meta tags specific to each subpage. By using template engines, developers can efficiently manage SEO elements for multiple subpages without duplicating code.

// Using Twig template engine to streamline SEO optimization for subpages

// Include Twig autoloader
require_once 'vendor/autoload.php';

// Initialize Twig loader and environment
$loader = new Twig_Loader_Filesystem('templates');
$twig = new Twig_Environment($loader);

// Render subpage with SEO metadata
echo $twig->render('subpage.twig', [
    'title' => 'Subpage Title',
    'description' => 'Description for subpage',
    'keywords' => 'keyword1, keyword2, keyword3',
    'canonical' => 'https://example.com/subpage',
    'image' => 'https://example.com/image.jpg'
]);
