php - Close session without writing or destroying it -

is there way close php session without either writing or destroying it? missing or there 2 functions (session_write_close() , session_destroy()) reset session_status() php_session_none? in other words, if have open session, can close without affecting external session data, can reloaded again.

you can $_session = null. session unavailable data remains (does not deleted).

consider have data in session:

<?php session_start(); session_regenerate_id(); // fresh id echo session_id();  $_session['test'] = '12345';  print_r($_session); // echoes data in session 

data: test|s:5:"12345";

then in next request:

<?php session_start(); echo session_id() . "<br>"; //  echoes same id of last request  $_session = null;  print_r($_session); // echoes nothing  echo "<br>";  echo session_status(); // echoes 2 (php_session_active) 

data still same: test|s:5:"12345";

(php-fpm 5.4.29, recent nginx, memcached session handler).

well data still can written through $_session['whatever'] = ... not read. i'm not sure whether solution have admit still don't understand why or whatfor need this.

as alternative, implement wrapper class session property $this->active = true; // or false:

class mysessionwrapper {     protected $active;     protected $data;     // getter setter $this->active , $this->data ...      public function getdata($var) {         if ($this->active !== true) {             throw new exception('session disabled');         }     } }
