I may have interpreted your problem incorrectly, but I think your
problem is due to the session data not being saved until the script
has finished running, including the system call. To get around this
you can save and close the session before calling system using the
session_write_close [1] function. Note that after calling that you
won't be able to make any other changes to the session data in that
