pass php variable value to javascript [duplicate]

Question

Im trying to pass the value of a php variable into javascript but i just cant get it to work. Am I doing anything wrong? Below is the line of code I'm working with.

var dist = parseInt("<?php echo json_encode($distance); ?>");

Answer 1

$distance is an integer? why don't you just write

var dist = <?php echo $distance; ?>

Answer 2

If the value in $distance is just an integer, you don't need the json_encode call. You can just do a php echo of $distance.

Something like

var dist = <?php echo $distance; ?>;
