How can beginners differentiate between PHP and HTML when creating new pages?

Beginners can differentiate between PHP and HTML by understanding that PHP is a server-side scripting language used for dynamic web content generation, while HTML is a markup language used for creating the structure of web pages. To incorporate PHP into HTML pages, beginners can use PHP opening and closing tags <?php ?> to execute PHP code within the HTML document.

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;PHP and HTML Example&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;h1&gt;Welcome to our website!&lt;/h1&gt;
    
    &lt;?php
        // PHP code to display current date
        echo &quot;Today is &quot; . date(&quot;Y-m-d&quot;) . &quot;&lt;br&gt;&quot;;
    ?&gt;
    
    &lt;p&gt;This is a paragraph written in HTML.&lt;/p&gt;
&lt;/body&gt;
&lt;/html&gt;
