There is no way to pass variables between PHP and JQuery.

But you can try something like this, it's not the best, but can set you on the right way. Get your data using PHP and place it in a DOM element like an input or div. Then access this DOM Element using Jquery

// Variable tha recieve the data
<?php $var = "Data"; ?>

// Placing the data in DOM
<input type='text' id='data' value='<?php echo $var ?>'>

// Retrieving using JQuery
<script>
    var data = document.getElementById('data').value;
    alert(data);
</script>
