That's not how PHP works. You can't mix client and server-side scripts that way. One option is creating a JavaScript variable:
<script>
var marks = <?php echo json_encode($MarkA);?>;
for(i=0;i<4;i++) alert(marks[i]);
</script>

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>
