What are the potential pitfalls of placing PHP code after </html> tag in terms of page loading and execution order?

Placing PHP code after the </html> tag can lead to unexpected behavior and errors in page loading and execution order. This is because the PHP code will still be executed by the server, even though the HTML page has already been rendered to the browser. To avoid these issues, all PHP code should be placed before the </html> tag to ensure proper execution order. 

&lt;?php
  // Place all PHP code before the &lt;/html&gt; tag
?&gt;
&lt;html&gt;
  &lt;head&gt;
    &lt;title&gt;Page Title&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
    &lt;h1&gt;Hello, World!&lt;/h1&gt;
  &lt;/body&gt;
&lt;/html&gt;
