Re: [PHP] Finding current PHP sessions From: Bogdan Stancescu (gutza <email protected>)
Date: 05/14/05

Ok, I went with the solution you recommended, by the way of a "thank
you" to the list, here's the resulting function:

/**
* This function returns the IDs of the current PHP sessions.
* At this time, it only works with
* { <email protected> http://www.php.net/manual/en/ref.session.php#AEN129461}
* PHP session.save_handler='files'
*
*  <email protected> Bogdan Stancescu
*  <email protected> http://opensource.org/licenses/lgpl-license.php GNU Lesser
General Public License
*
*  <email protected> mixed false on error or the indexed array of the session IDs;
* please note that the session IDs are 16-bit values represented as
* 32-character long hexadecimal strings; letters are in lower caps.
*/
function getCurrentSessionIDs()
{
   if (ini_get('session.save_handler')!='files') {
     // sorry, we only know how to handle files at this time!
     return(false);
   }
   $sessions=array();
   $session_path=session_save_path();
   $d = dir($session_path);
   while (false !== ($entry = $d->read())) {
     if (
       ($entry=='.') ||
       ($entry=='..') ||
       (!is_file("$session_path/$entry"))
     ) {
       continue;
     }
     if (preg_match("/^sess_([0-9a-f]{32})$/",$entry,$matches)) {
       $sessions[]=$matches[1];
     }
   }
   return($sessions);
}

Cheers,
Bogdan
