If the side is being processed through PHP (on the server) you can just use an echo
<pre>
<script>
$(document).ready(function(){
var timeLeft = <?php echo 12796; ?>;
console.log(timeLeft);
});
</script>
After PHP has processed the page it is just regular javascript as if you wrote it manually.
You can also imagine the following example:
<html>
<head>
<script type="text/javascript">
alert('<?php echo 'hello js' ?>');
</script>
</head>
<body>
</body>
</html>
Save it as hello.php inside of your web servers document root and call it in browser.
