php - SESSION variables not passed from page after destroying the rest -

-

i @ total loss words.

i allow admin reset registration if reaching error during process. in theory, following code should function this:

page reached, $adminvalidated set based on session data. $_session array cleared; cookie cleared on consumer end; session id regnerated , session destroyed. session restarted , mentioned variable put session.

the "echo" statements included below work when redirect page (commented out below), session variables not carry over.

yes have started session on follow page well.

<?php     session_start();     ob_start();     if( $_server['server_port'] == 80) {         header('location:https://'.$_server['http_host'].$_server["request_uri"]);          die();     }       $adminvalidated = $_session['adminvalidated'];      $_session = array();      if (ini_get("session.use_cookies")) {         $params = session_get_cookie_params();         setcookie(session_name(), '', time() - 42000,             $params["path"], $params["domain"],             $params["secure"], $params["httponly"]         );     }      session_regenerate_id(true);     session_destroy();     session_start();      $_session['adminvalidated'] = $adminvalidated;      echo $_session['adminvalidated'];  /*     header("location: ../a.php");     exit;*/ ?>

in general suffices call session_regenerate_id(true) change session id of current session and invalidate association previous session id.

if additionally want clear session data except $_session['adminvalidated'], this:

session_regenerate_id(true); $_session = array(     'adminvalidated' => $_session['adminvalidated'] );
