How can beginners improve their understanding of the syntax required to include PHP variables in HTML?

Beginners can improve their understanding of including PHP variables in HTML by practicing with simple examples. They can start by declaring a variable in PHP and then echoing it within HTML using the `<?php echo $variable; ?>` syntax. By experimenting with different variable types and placements within HTML elements, beginners can gain a better grasp of how PHP variables can be integrated into HTML code.

&lt;?php
$name = &quot;John Doe&quot;;
?&gt;

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;PHP Variable in HTML&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;h1&gt;Welcome, &lt;?php echo $name; ?&gt;!&lt;/h1&gt;
&lt;/body&gt;
&lt;/html&gt;
