Accessing session data outside Joomla

Question

I am trying to run an application outside Joomla (not as a plugin) and I would like to access the logged in user\'s information (userid). I am wondering how should I go abou

First of all you have to provide definition to some joomla's constants(identifiers) as follows:

define( '_JEXEC', 1 );
define( 'DS', DIRECTORY_SEPARATOR );
define( 'JPATH_BASE',$_SERVER['DOCUMENT_ROOT'].DS. basename(dirname(__DIR__)) );

where: JPATH_BASE is represents your site's root directory. It must be correct.

After than, you have to use key files as follows:

require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );

After than, you have to create an application object and initialize it also:

$mainframe =& JFactory::getApplication('site');
$mainframe->initialise();  

[this is optional] If you want to import some other libraries, then you can do this as follows:

jimport( 'joomla.user.user');
jimport( 'joomla.session.session');
jimport( 'joomla.user.authentication');

So the core code for your file is as follows:

define( '_JEXEC', 1 );
define( 'DS', DIRECTORY_SEPARATOR );
define( 'JPATH_BASE',$_SERVER['DOCUMENT_ROOT'].DS. basename(dirname(__DIR__)) );

require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );

$mainframe =& JFactory::getApplication('site');
$mainframe->initialise();

//optional use depend on requirement 
jimport( 'joomla.user.user');
jimport( 'joomla.session.session');
jimport( 'joomla.user.authentication');
