You cannot use client side script variable into server side script. But you can parse the PHP array using the below method. No need javascript increment variable.

<?php $MarkA = array(1,2,3,4);?>

<script>
var json = JSON.parse("<?php echo json_encode($MarkA);?>");

$.each(json,function (i,item) {
    console.log(item);
});
</script>
