Are there any best practices for handling radio buttons in PHP form submissions?

When handling radio buttons in PHP form submissions, it's important to ensure that only one option can be selected at a time. One way to achieve this is by giving each radio button in the group the same name attribute and different values. Then, in the PHP form processing code, you can check which radio button was selected by accessing the value of the name attribute. 

<form method="post">
  <input type="radio" name="gender" value="male"> Male
  <input type="radio" name="gender" value="female"> Female
  <input type="submit" name="submit" value="Submit">
</form>

<?php
if(isset($_POST['submit'])){
  $selectedGender = $_POST['gender'];
  echo "Selected gender: " . $selectedGender;
}
?>
