    You cannot use the variable first and the initialize later in php. For the same effect efficiently you can do something like.

    <div>Total class: <span><?php echo count($row->newsSources); ?></span>
<div>Total student: <span>237</span>
//rest of the code

    It is still not very clear what you are asking, but I think you want to render your html within the first loop, after the nested loop compleats. You can break the php code block after the nested loop ?> <?php or use echo.

    <?php
    foreach($cursor as $row) {
        $count = 0;
        foreach($row->class as $item) {
            $count+= count($row->class);
        }

        ?>
            <div>Total class: <span><?php echo $count; ?></span>
            <div>Total student: <span>237</span>
        <?php
    }
?>

    You can change your HTML code like this:

    <div>Total class: <span id="count">$count</span>
<div>Total student: <span>237</span>

    and then create JavaScript code like this to set the value.

    Edit: JavaScript code by PHP

    document.getElementById("count").innerHTML = variable;
