How can PHP developers monitor and analyze website traffic to improve performance and user experience?

To monitor and analyze website traffic to improve performance and user experience, PHP developers can implement Google Analytics tracking code on their website. This will allow them to track various metrics such as page views, bounce rate, and user demographics. By analyzing this data, developers can identify areas for improvement and make data-driven decisions to enhance the website's performance and user experience.

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