How can radio buttons and dropdown fields be used together in a PHP form?

Radio buttons and dropdown fields can be used together in a PHP form by allowing the user to select options from both input types. To implement this, you can group the radio buttons together and give them the same name attribute, while each dropdown field should have a unique name attribute. When the form is submitted, you can check which radio button was selected and retrieve the selected option from the dropdown field. 

<form method="post" action="process_form.php">
  <input type="radio" name="radio_option" value="option1"> Option 1
  <input type="radio" name="radio_option" value="option2"> Option 2

  <select name="dropdown_option">
    <option value="dropdown_option1">Dropdown Option 1</option>
    <option value="dropdown_option2">Dropdown Option 2</option>
  </select>

  <input type="submit" value="Submit">
</form>
