php - Unable to get session contents in second function -

i having issues sessions.

in first function queue, save session entries can print out function, can see being set correctly.

in function remove, try , save entries session variable , error entries undefined index.

does have ideas doing wrong here?

function queue()  {     session_start();      $status = 'awaiting moderation';     $channel = '1';      // find entries in 'gallery' channel 'awaiting moderation' status     $this->ee->db->select('entry_id')                  ->from('exp_channel_titles')                  ->where('status', $status)                  ->where('channel_id', $channel);      $query = $this->ee->db->get();           $entries = $query->result_array();      $entries_count = count($entries);      // set count     $_session['entries_count'] = $entries_count;          // if entries found     if ($entries_count > 0)     {         // flatten entry ids array         $entriesflat = array();         array_walk_recursive($entries, function($a) use (&$entriesflat) { $entriesflat[] = $a; });          $entriesserial = serialize($entriesflat);          // save in session         $_session['entries'] = $entriesserial;     }  }  function remove() {     session_start();      // session data + save variable     $entries = $_session['entries'];  } 

you can have 1 session , should @ top of file.
