What is the best practice for evaluating checkboxes with unknown names in a PHP form?

When dealing with checkboxes in a PHP form that have unknown names, it is best to loop through all the form inputs and check for checkboxes using the isset() function. This way, you can dynamically evaluate the checkboxes without knowing their names beforehand. 

// Loop through all form inputs
foreach ($_POST as $key => $value) {
    // Check if the input is a checkbox
    if (isset($_POST[$key]) && $_POST[$key] == 'on') {
        // Checkbox is checked, perform desired action
        echo "Checkbox with name $key is checked.";
    }
}
