How can the use of radio buttons and checkboxes in PHP forms affect data manipulation?

Radio buttons and checkboxes in PHP forms can affect data manipulation by allowing users to select multiple options or only one option from a list. To handle these inputs correctly, you need to ensure that your PHP code properly processes the values sent by these form elements. Use conditional statements to check which options were selected and handle the data accordingly in your backend processing. 

// Example PHP code snippet to handle radio buttons and checkboxes in a form submission

if(isset($_POST['radio_option'])){
    $selected_radio_option = $_POST['radio_option'];
    // Process the selected radio option
}

if(isset($_POST['checkbox_options'])){
    $selected_checkbox_options = $_POST['checkbox_options'];
    // Process the selected checkbox options (which may be an array)
    foreach($selected_checkbox_options as $checkbox_option){
        // Process each selected checkbox option
    }
}
