How can PHP scripts be optimized to prevent self-loading and display issues in templates?

To prevent self-loading and display issues in templates, PHP scripts can be optimized by separating logic from presentation. This can be achieved by using a templating engine like Twig or Smarty, which allows for cleaner and more organized code. By keeping PHP logic separate from HTML markup, it becomes easier to maintain and debug the code, reducing the risk of self-loading and display issues.

// Example of separating logic from presentation using Twig templating engine
require_once 'vendor/autoload.php';

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

$data = [
    'title' => 'Welcome to our website',
    'content' => 'This is some sample content',
];

echo $twig->render('index.html', $data);
