Actually  it works  but you also need to do   SESSION   array    after the session destroy to get rid of   SESSION variables  However  avoid doing unset   SESSION  because that makes sessions useless

After using session destroy    the session is destroyed behind the scenes  For some reason this doesn t affect the values in   SESSION  which was already populated for this request  but it will be empty in future requests   You can manually clear   SESSION if you so desire    SESSION

I had to also remove session cookies like this   session start       SESSION            If it s desired to kill the session  also     delete the session cookie      Note  This will destroy the session  and     not just the session data   if  ini get  session use cookies            params   session get cookie params         setcookie session name        time   - 42000            params  path     params  domain              params  secure     params  httponly                   Finally  destroy the session   session destroy      Source  geeksforgeeks org

It works   but sometimes it doesn t  check the below example    lt  php session start      SESSION  name    shankar   if isset   SESSION  name           echo   SESSION  name       Outputs shankar   session destroy    echo   SESSION  name       Still outputs shankar   Weird   Right    How to overcome this    In the above scenario   if you replace session destroy    with unset   SESSION  name     it works as expected   But i want to destroy all variables not just a single one    Yeah there is a fix for this too  Just unset the   SESSION array   Credits Ivo Pereira   unset   SESSION

Well  this seems a new problem for me  using a new php server   In the past never had an issue with sessions not ending   In a test of sessions  I setup a session  ran a session count   and closed the session   Reloaded the page and to my surprise the variable remained   I tried the following suggestion posted by mc10  session destroy      SESSION   array       Clears the   SESSION variable   However  that did not work   I did not think it could work as the session was not active after destroying it  so I reversed it     SESSION   array    session destroy      That worked  reloading the page starting sessios and reviewing the set variables all showed them empty not-set   Really not sure why session destroy   does not work on this PHP Version 5 3 14 server   Don t really care as long as I know how to clear the sessions

If you need to clear the values of   SESSION  set the array equal to an empty array     SESSION   array      Of course  you can t access the values of   SESSION on another page once you call session destroy  so it doesn t matter that much   Try the following   session destroy      SESSION   array       Clears the   SESSION variable
