I'm trying to figure out I how can do something like:

console.log('<?php print_r($_SESSION); ?>');

To see the results in the console.

console.log('<?php echo serialize($_SESSION); ?>');

does not work either. Is there a way for me to echo the session information in firebug or inspect element in chrome for testing purposes?

    are you using this code between script tags? – ahmet2106 Dec 29 '11 at 22:26

    Not working does not qualify as a correct description about the error you face. You can not just throw anything out as javascript "string" and then expect it to work. Imagine there is a `'` inside the serialized string, it would just make it stop working. – hakre Dec 29 '11 at 22:33

You could try this :

<script>
    console.log(<?php echo json_encode($_SESSION, JSON_HEX_TAG); ?>);
</script>

No quotes are required. See as well Firebug and Logging.

[edit, May 2014] Updated the code to be safe against XSS attacks. Always pass JSON_HEX_TAG to json_encode if you're embedding in HTML, or an attacker could inject code into the DOM by having you encode a string like:

</script><script>alert('Hello!');

It is not possible to view the session details using fire bug.

    Actually this answer is pretty correct by its nature and doesn't deserve to be downvoted, since it is really not possible to view the session data using only firebug - your serverside should prepare the data. And in this case the question makes no sense, because you can prepare anything: data from session, db, 3rd party service, etc – zerkms Dec 29 '11 at 22:36
  • In Chrome it's easily accessible under the Application tab. Is this still missing from Firebug? I understand that I could view it on server side, but it'd be easier to see it like in Chrome. – Csaba Toth Sep 05 '17 at 23:43
