Are there any alternative methods to using JavaScript for automatically submitting preselected radio buttons in PHP forms?

One alternative method to using JavaScript for automatically submitting preselected radio buttons in PHP forms is to use hidden input fields to store the selected value and then submit the form using PHP. This can be achieved by setting the value of the hidden input field to the selected radio button value when the form is submitted. 

<form method="post" action="submit.php">
    <input type="radio" name="option" value="option1" checked> Option 1
    <input type="radio" name="option" value="option2"> Option 2
    <input type="hidden" name="selected_option" id="selected_option">
    <input type="submit" value="Submit">
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $selectedOption = $_POST['selected_option'];
    // Process the selected option here
}
?>
<script>
    document.getElementById('selected_option').value = document.querySelector('input[name="option"]:checked').value;
</script>
