Are there any best practices to follow when embedding PHP in HTML?

When embedding PHP in HTML, it is important to follow best practices to ensure clean and maintainable code. One common best practice is to separate PHP logic from HTML presentation by using PHP tags only for dynamic content and keeping HTML markup separate. Additionally, it is recommended to use short tags "<?php ?>" instead of "<? ?>" for better compatibility with different server configurations. Lastly, make sure to properly sanitize user input to prevent security vulnerabilities.

&lt;head&gt;
    &lt;meta charset=&quot;UTF-8&quot;&gt;
    &lt;title&gt;User Profile&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;h1&gt;Welcome, &lt;?php echo htmlspecialchars($name); ?&gt;!&lt;/h1&gt;
    &lt;p&gt;You are &lt;?php echo $age; ?&gt; years old.&lt;/p&gt;
&lt;/body&gt;
&lt;/html&gt;
