How can radio buttons be displayed from a form in PHP?

To display radio buttons from a form in PHP, you can use the HTML `<input type="radio">` element within a PHP echo statement. You can set the `name` attribute to group the radio buttons together and the `value` attribute to specify the value of each radio button. To pre-select a radio button, you can add the `checked` attribute to the desired radio button. 

&lt;form action=&quot;process_form.php&quot; method=&quot;post&quot;&gt;
  &lt;input type=&quot;radio&quot; name=&quot;gender&quot; value=&quot;male&quot; checked&gt; Male
  &lt;input type=&quot;radio&quot; name=&quot;gender&quot; value=&quot;female&quot;&gt; Female
  &lt;input type=&quot;radio&quot; name=&quot;gender&quot; value=&quot;other&quot;&gt; Other
  &lt;input type=&quot;submit&quot; value=&quot;Submit&quot;&gt;
&lt;/form&gt;
