Yii overwrite accessRules in base class

leave a comment »

Suppose you defined a base class Controller with basic accessRules

class Controller extends CController
  public function filters()
    return array(
      'postOnly + delete',

  public function accessRules() {
    return array(
      // allow authenticated user to perform 'create' and 'update' actions
      array('allow', 'actions'=>; array('index', 'view'), 'users' => '@'),

      // deny all users
      array('deny', 'users'=>'*'),

and you want to add (overwrite) rules in derived class, using array_merge here how you do it:

class Site extends Controller
  public function accessRules()
    return array_merge(
      // allow all user to perform 'help' actions
      array( array('allow', 'actions'=> array('help'), 'users' => '*') ),

      // parent go last

As best practice your base class default access rule is deny all by default.

PHP date diff

with 2 comments

I call out for an excuse for not practicing PHP enough recent year; with just a simple date_diff could knock me out :) not to open my complain of having different version of PHP to check before using a function(s) I got a request from a friend to help workout how many days from two given date.

Now if I have two date string (it is what we get from form post right?)

// fixed format as I don't want to deal with complicate of different world format :(
$day1 = "26/03/2009";
$day2 = "28/03/2009";
// now I need to know how many days does it take from day1 to day2
// PHP 4.x; ignore my out of date PHP skill this is how I did it
$break_day1_apart = explode('/', $day1);
$break_day2_apart = explode('/', $day2);
$day1_number_form = $break_day1_apart[2].$break_day1_apart[1].$break_day1_apart[0];
$day2_number_form = $break_day2_apart[2].$break_day2_apart[1].$break_day2_apart[0];

$day_diff = abs((int)$day2_number_form - (int)$day1_number_form);

// and it should work by theory
echo $day_diff; 

Suck ! what would you do instead?
