How can PHP developers ensure that their code follows the current HTML standards when creating shapes like circles?

PHP developers can ensure that their code follows the current HTML standards when creating shapes like circles by using the HTML <svg> element with the <circle> element inside it. This allows for the creation of scalable vector graphics that adhere to modern web standards. 

&lt;?php
echo &#039;&lt;svg height=&quot;100&quot; width=&quot;100&quot;&gt;
  &lt;circle cx=&quot;50&quot; cy=&quot;50&quot; r=&quot;40&quot; stroke=&quot;black&quot; stroke-width=&quot;3&quot; fill=&quot;red&quot; /&gt;
&lt;/svg&gt;&#039;;
?&gt;
