How can PHP code syntax impact the functionality of HTML elements like the <a> tag?

The PHP code syntax can impact the functionality of HTML elements like the <a> tag if not properly integrated. To ensure that PHP code does not interfere with HTML elements, it is crucial to properly concatenate PHP variables or functions within the HTML code. This can be achieved by using echo statements or closing and reopening PHP tags within the HTML code.

&lt;?php
$website = &quot;https://www.example.com&quot;;
echo &quot;&lt;a href=&#039;$website&#039;&gt;Click here&lt;/a&gt;&quot;;
