php - How to get the array of a 2d array in codeigniter -


i have model, 

function getdata($id) {     $arr=array(array());     $sql = "select id, title topic ....";     $query = $this->db->query($sql,array($id));     $arr[0][0] = $query->result();     $sql = "select id, title topic ....";     $query = $this->db->query($sql,array($id));     $arr[0][1] = $query->result();     return $arr; }

and in controller, have code,

$data['check'] = $this->model->getdata("21313"); ... $this->load->view('check',$data);

how can echo data?

i tried, 

foreach($check[0][0] $row) {     echo $row->id;     echo $row->title; }

but not working.

try print_r($data); first on controller

and check structure if $check model result can on view

foreach($check $row) {     echo $row->id;     echo $row->title; }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
