How can i use count function with autoincrement?

Question

I am working on a php situation that i have. What it should do is like. each product has a unique id value. if the product id is posted throught submit button, A count action should be activited to count the number of time that product id is posted, so increment.

I hope i exposed the situaation clearly. This is the way i thought doing it, but can't get it work:

<?php

if (isset($_POST['submit'])) {

 $do = count($_POST['id']);

  echo $do;

  if ($do > 1)
 {

  $i= $do+1;

   echo $i;
 }
}


?>

If I assume the value in the hidden input #id is the times users vote the product:

if (isset($_POST['submit'])) {
 $do = count($_POST['id']);
  echo $do++;
}

If I assume it incorrectly I don't understand what you want to do, sincerly.
