I am making a game for my computing class. The user has to change settings of their robot before playing.

As the settings file where the user customises their robot is a separate PHP file I was wondering if there was a way to assign the $_SESSION variables to JavaScript variables like so:

var tractionType = <?php echo $_SESSION['traction']; ?>; ...

Is this possible?

    Should work fine, just remember to quote it if it's a string Commented Mar 30, 2014 at 18:29

Sure, you can either create the whole JS file from PHP, as in

<script type="text/javascript" src="js/settings.php"></script>

or you put those variables inline

<script type="text/javascript">
 var my_variable=<?=(int)$_SESSION['my_variable']?>;
</script>
