How can PHP code be optimized to prevent errors like missing or replaced content in templates?

To prevent errors like missing or replaced content in templates, PHP code can be optimized by using a templating engine like Twig. Twig separates the logic from the presentation, making it easier to manage and update templates without affecting the PHP code. By using Twig, variables are securely passed to templates, reducing the chances of missing or replaced content issues. 

// Example PHP code using Twig templating engine
require_once 'vendor/autoload.php';

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

$template = $twig->load('index.html');
echo $template->render(['title' => 'Welcome', 'content' => 'Hello World']);
