How can the selection from radio buttons or checkboxes be evaluated in PHP using $_GET or $_POST?

When using radio buttons or checkboxes in a form, the selected value can be accessed in PHP using the $_GET or $_POST superglobals. To evaluate the selection, you can check if the corresponding key is set in the superglobal array and then retrieve the selected value. This allows you to perform actions or make decisions based on the user's selection. 

// Example code to evaluate selection from radio buttons or checkboxes using $_POST

if(isset($_POST['radio_button'])) {
    $selected_option = $_POST['radio_button'];
    // Perform actions based on the selected option
}

// Example code to evaluate selection from checkboxes using $_POST

if(isset($_POST['checkbox'])) {
    $selected_options = $_POST['checkbox'];
    // Perform actions based on the selected options
}
