This wouldn't work. The jQuery is being executed on the client-side, after the page has been loaded in a browser, after all php processing has completed. By the time jQuery is being processed, php processing has finished.

I would suggest performing the functionality all in javascript/jQuery if possible. If not, consider using jQuery's load function to get the contents of a php script executed with that var.

E.g.: test.php:

<?PHP 
    function myphpfunction($v){
    // Some processing here
    return 1;
    }
echo myphpfunction($_GET['v']); 
t?>

Your jQuery:

<script>
var CIV = parseInt($("#mydiv").attr("data-id"));
if(CIV < 4) { var CIF = CIV += 1; } else { var CIF = 1; }

$("#mydiv").load('test.php?v='+CIF);

</script>
