Is it recommended to use frames in PHP for website development, considering the discussion around Google Analytics tracking code placement?

Using frames in website development is generally not recommended due to various issues such as SEO problems, accessibility concerns, and difficulty in tracking user behavior accurately with tools like Google Analytics. It is better to use modern techniques like CSS for layout and AJAX for dynamic content loading. To ensure proper tracking with Google Analytics, the tracking code should be placed directly in the HTML of each page.

// Google Analytics tracking code snippet
<script async src="https://www.googletagmanager.com/gtag/js?id=GA_TRACKING_ID"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'GA_TRACKING_ID');
</script>
