How can dynamic radio buttons in PHP be evaluated to determine user selection?

To evaluate dynamic radio buttons in PHP to determine user selection, you can use the isset() function to check if the radio button has been selected. You can then retrieve the selected value using $_POST or $_GET superglobals. 

<form method="post">
<?php
$radio_options = array("Option 1", "Option 2", "Option 3");

foreach ($radio_options as $option) {
    echo '<input type="radio" name="radio_option" value="' . $option . '">' . $option . '<br>';
}

if (isset($_POST['radio_option'])) {
    $selected_option = $_POST['radio_option'];
    echo 'You selected: ' . $selected_option;
}
?>
<input type="submit" value="Submit">
</form>
