pass php variable value to javascript

I want to create a progress bar, the value of the progress will be coming from PHP.

<div class="prog" id="progressbar"></div>
<label id="amount">
<?php echo $cast; ?></label>

I have this kind of javascript.

<script>
$(function() {
    $( "#progressbar" ).progressbar({
    value: 0
    });
});
</script>

How can I throw the value $cast in my script?

Javascript is run in Client (browser), while PHP is run on server. You can't cast varble from PHP to javascript like that. With print progress:

 <?php echo $cast; ?>

it just display the value of current run time, it is not updated. If you have a link to check value of progress bar, just use ajax POST or GET to make change.
