Getting count of Checkbox array in php, displaying specific value in textbox

is there a way i can get the count of an array of checkboxes, say there are like 4 arrays(yeswb[], yesab[], yesal[], yesvb[]). In need to get the count of the arrays yeswb[], yesab[], yesal[] and yesvb[], compare the largest count amongst them and display a specific value on a textfield.

<form action="checkbox.php" method="POST">
                        <table class="table table-striped table-bordered table-hover" id="dataTables-example">
                                    <thead>
                                        <tr>
                                        <th>Indicator/Symptom</th>
                                            <th>Yes</th>
                                            <th>No</th>
                                        </tr>
                                    </thead>

                                    </tbody>
                                </table> 
                                </form> 

say for example the count of yeswb[] is 4, the count of yesab[] is 3 and the count of yesvb[] is 1, how will I generate a statement like yeswb[] wins in a textfield? (because with a count of 4 yeswb[]is the greatest) thank you in advance.
