php - apply codes to all controller in codeigniter -


i have simple code place in controller's constructor

$this->output->set_header("cache-control: no-store, no-cache, must-revalidate, no-transform, max-age=0, post-check=0, pre-check=0"); $this->output->set_header("pragma: no-cache");

i use code safety of logout. question is, there way put/declare code global each of controllers? because hard hard code on each controller's constructor.

thank help.

i answers best approach use hooks. first add hooks.php

 $hook['display_override'] = array(     'class'    => 'routeprocess',     'function' => 'afterroute',     'filename' => 'routeprocess.php',     'filepath' => 'hooks',     'params'   => array()  );

then go hooks/ folder , create routesprocess.php create file below:

class routeprocess{ function afterroute(){     $this->ci =&get_instance();      $this->ci->output->set_header("cache-control: no-store, no-cache, must-revalidate, no-transform, max-age=0, post-check=0, pre-check=0");     $this->ci->output->set_header("pragma: no-cache");     echo $this->ci->output->get_output(); } }

the thing not require __construct() of controller called can overridden. called no matter what.

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.
