If you need to encode non-scalar values (such as arrays, objects or just about anything), you can use json_encode():

<script type="text/javascript">
    <?php
        $next_exp = array(1, 2, 3);
        echo 'var next_exp = ' . json_encode($next_exp);
    ?>
    // next_exp is now a usable JavaScript array: [1, 2, 3]
</script>
