php - Can't change session value in codeigniter -

this question has answer here:

• codeigniter modifying session data 3 answers

i use session in codeigniter, works can't change value. use function :

$this->session->set_userdata('check', 0); 

i must change value of 'check' 0.

why can't ?

my question is, why can't change value session ? , set value first time :

$sess_array = array(         'userid' => $row->userid,         'pseudo' => $row->pseudo,         'check'  => $row->check );   $this->session->set_userdata('logged_in', $sess_array); 

$sess_array = array(     'userid' => $row->userid,     'pseudo' => $row->pseudo,     'check'  => $row->check );  // have set session key 'logged_in'  $this->session->set_userdata('logged_in', $sess_array);  // session value existing key $arrsession = $this->session->userdata('logged_in'); $arrsession['check'] = 0; $this->session->set_userdata('logged_in', $arrsession); 

you need update value shown above.

if wish set 'check' value indicated. need following

$sess_array = array(     'userid' => $row->userid,     'pseudo' => $row->pseudo,     'check'  => $row->check );  // note no key specified.  $this->session->set_userdata($sess_array); // think can set check value. give try. let me know works. $this->session->set_userdata('check',0);
