How can syntax errors, such as unexpected variables, be avoided when working with PHP variables in HTML?

To avoid syntax errors such as unexpected variables when working with PHP variables in HTML, always ensure that variables are properly enclosed within PHP tags when being echoed out in HTML. This can be achieved by using the `<?php echo $variable; ?>` syntax to output variables within HTML code. 

&lt;?php
$variable = &quot;Hello, World!&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;&lt;?php echo $variable; ?&gt;&lt;/h1&gt;
&lt;/body&gt;
&lt;/html&gt;
