Why not sample the session varibles of a PHP file that is in the same directory from another PHP file if it shows?

Question

I have a Drupal site

mydomain.com/

Within a block full php I have the following:

<?php
session_start ();
echo json_encode($_SESSION['playlist']); 
?>

This code shows me correctly my array inside the session varible example:

[
    "{\"title\":\"emo\",\"artist\":\"a href=\",\"mp3\":\"\"}",
    "{\"title\":\"emo\",\"artist\":\"a href=\",\"mp3\":\"\"}",
    "{\"title\":\"Hablando Claro Pegando Fuerte\",\"artist\":\"\",\"mp3\":\"http://red.comppa.com/sites/default/files/audios/01%20radionovela%20hablando%20claro%20pegando%20fuerte.mp3\"}",
    "{\"title\":\"desobedicia\",\"artist\":\"a href=\",\"mp3\":\"\"}"
]

But if I have another file called getsession.php with the same code:

<?php
session_start ();
echo json_encode($_SESSION['playlist']); 
?>

Then I dirigo to mydomain.com/getsession.php and shows me:

null

Are you setting the session on the same page the same way on both files? — Jordan, Mar 22 '13 at 20:05

solved with :

<?php
//set the working directory 
chdir('/home/www/mydrupal/');
define('DRUPAL_ROOT', getcwd());

//Load Drupal
require_once './includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);

echo json_encode($_SESSION['playlist']); 
?>

Check the order that your files are being included. It is possible that you are trying to echo the values of the session before it has been set.

session_start

If a session fails to start, then FALSE is returned. Previously TRUE was returned. (Source)

Perhaps, content was sent to the browser BEFORE session_start was called. This will generate an error as a result!
