What are the best practices for integrating PHP code into existing HTML pages?

When integrating PHP code into existing HTML pages, it's important to ensure that the PHP code is properly embedded within the HTML structure. One common way to do this is by using PHP opening and closing tags <?php ?> to enclose the PHP code. Additionally, it's recommended to separate PHP logic from HTML presentation by keeping the PHP code at the top of the file or in a separate PHP file and using PHP echo or print statements to output dynamic content within the HTML. 

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;PHP Integration&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;h1&gt;Welcome &lt;?php echo &quot;User&quot;; ?&gt;&lt;/h1&gt;
    &lt;p&gt;&lt;?php 
        $date = date(&quot;Y-m-d&quot;);
        echo &quot;Today&#039;s date is: &quot; . $date; 
    ?&gt;&lt;/p&gt;
&lt;/body&gt;
&lt;/html&gt;
