Not a simple way  no   Let s say that by  active  you mean  hasn t passed the maximum lifetime  and hasn t been explicitly destroyed and that you re using the default session handler    First  the maximum lifetime is defined as a php ini config and is defined in terms of the last activity on the session  So the  expiry  mechanism would have to read the content of the sessions to determine the application-defined expiry  Second  you d have to manually read the sessions directory and read the files  whose format I don t even know they re in    If you really need this  you must implement some sort of custom session handler  See session set save handler   Take also in consideration that you ll have no feedback if the user just closes the browser or moves away from your site without explciitly logging out  Depending on much inactivity you consider the threshold to deem a session  inactive   the number of false positives you ll get may be very high

echo   lt pre gt    var dump   SESSION   echo   lt  pre gt      Or you can use print r if you don t care about types  If you use print r  you can make the second argument TRUE so it will return instead of echo  useful for     echo   lt pre gt     print r   SESSION  TRUE      lt  pre gt
