How do I pass a php variable in an array to javascript?

I'm trying to pass a PHP variable to Javascript like this..

var url = <?php echo $urlArray[0]; ?>;

The contents of $urlArray[0] is a string from a json decoded array

"baby"

When I run the code I get the error..

Uncaught ReferenceError: baby is not defined

var url = "<?php echo $urlArray[0]; ?>";

you forgot the quotes.

If you need to export more complicated data structure, you may need json_encode. This might be helpful if exporting arrays and/or objects.

json_encode is your friend - use to wrap anything you're trying to pass to javascript.

http://php.net/manual/en/function.json-encode.php

var url = <?php echo json_encode($urlArray[0]); ?>;
