What attributes in an HTML form should be considered when evaluating radiobuttons in PHP?

When evaluating radiobuttons in PHP, it is important to consider the "name" attribute of the radiobutton input elements. This attribute is used to group related radiobuttons together so that only one option can be selected at a time. Additionally, the "value" attribute should be set to a unique value for each radiobutton option to differentiate between them when processing the form data in PHP. Lastly, the "checked" attribute can be used to pre-select a radiobutton option if needed. 

<form action="process_form.php" method="post">
  <input type="radio" name="gender" value="male" checked> Male<br>
  <input type="radio" name="gender" value="female"> Female<br>
  <input type="radio" name="gender" value="other"> Other<br>
  <input type="submit" value="Submit">
</form>
